**A composite functions calculator** is a **software-based** mathematical tool, that you can use to evaluate composite functions.

Functions are said to be composite when one output of the first function becomes the input of the second function.

Composition of functions is a slightly advanced level mathematical concept that is taught to students a little late in their academics.

Composite functions are not an old concept like Trigonometry or algebra itself, this concept was put forward by **A.N. Kolmogorov** in **1956** and has been in use ever since.

Although the concept and name of the functions might seem a bit complicated you use composite functions in your daily life without even realizing it.

For example, calculating the discount on a shirt that you like and determining whether you can afford it or not.

Composite functions, just like the rest of mathematics, are something that we constantly use in our daily lives.

But, the technical terms might confuse some individuals, and that is where a composite function calculator comes in handy.

You can use a composite function calculator to solve a composite function problem just by entering the data that you have from the question, and the rest will be done by the calculator.

There are a lot of composite function calculators that you can find online, almost all the math and calculator websites have one.

But if you don’t want to waste your time searching for a calculator instead of using it, this article is for you.

In this **article**, some really great calculators have been mentioned and a small review for each of them has also been given below, highlighting their pros and cons so you can find the best composite functions calculator for yourself.

Hopefully, after reading this article you will be able to find the best calculator for yourself and composite functions problems won’t be a hassle for you anymore.

## Best Composite Functions Calculator

**1. eMath Help: Composite Function Calculator**

**eMath Help** is a website that focuses on mathematical tools and methods. You can find a wide range of calculators on almost all the major math subjects like; Algebra, Geometry, Calculus, Discrete Math, etc.

In addition to the calculators and tools, you can also find games and notes related to these topics which can further strengthen your grasp of these topics.

eMath Help is a really informative website and supports one of the **best composite functions calculators**.

The calculator has a simple design and is nothing more than an input box and a keyboard. Make sure you define your functions in their respective boxes, the boxes are labeled as **f,g**, and **h**.

You can see how the calculator reads f and g for your calculations on the top of the calculator, it is really simple to use this calculator and you won’t face any problems.

The calculator that eMath Help uses for its functions is actually supported by Symbolab which is another really great calculator website.

The design of the website isn’t that great visually but does okay on the practical side.

You can easily tell that little attention was given to the website’s design as most of it is organized. But all the contents of the website are easily accessible and it runs pretty smoothly.

Once you have entered your functions in the input sections click ‘Calculate’ and you will your answers below.

The results won’t only contain the final answer but also the full solution. You also have the option to input a value if you want to solve the functions.

**2. AtoZMath: Composite Functions and Evaluating Functions**

**AtoZMath** is a website sort of like eMath Help that we discussed above. But this is a slightly less popular website.

However, that does not at all make it any less capable than the rest of the websites on this list

It has the same content as every other mathematical website. These include tools, calculators, mathematical games, word problems, and guides for different methods.

On the webpage of the composite function calculator, you’ll have a bunch of calculators. Make sure you use the second calculator in the calculator section as that is the one you’ll need.

The design of AtoZMath’s composite function calculator is pretty basic. You won’t find any colors or design details which may seem a little boring, but the calculator is also fairly simple to use.

From the design point of view, AtoZMath might be the worst website on this list. Not only is the website unorganized but has unnecessary writing and buttons.

The whole website seems congested and overwhelming. It’s hard to believe that AtoZMath is a credible website just by looking at its design. Even some of the fonts on the website are pixelated.

Once you have entered both of the functions make define which function is going to be the input of the other function and then click ‘Find’.

You will get the simplified function below with a few steps on the solution, if you want the complete solution you will have to make an account.

**3. Calculator-Online: Composite Function Calculator**

Both the calculators that have been discussed until now are supported by websites that are totally dedicated to Math.

**Calculator-Online** is a website that deals with all sorts of calculators in addition to a wide of mathematical Calculators you can find calculators related to health, physics, chemistry, stats, conversions, etc.

Calculator online is actually one of the most widely used calculator websites on the internet, and its composite function calculator can be an excellent choice for you.

This calculator has the simplest UI out of all the calculators on this list. You just need to enter the **f function**, the **g function**, and a point for which you want to solve the function.

The design of the calculator is pretty basic, which also makes it easy to use and provides an adequate user experience.

Apart from the inputs and the action button there really isn’t any else to the calculator.

As** Calculator-Online** is a popular website that is trusted by thousands of people worldwide you would expect it to have a really good website design, but unfortunately, it doesn’t.

The first thing that you’ll notice as soon as you enter the website is the huge number of advertisements on the website.

From top to bottom and around the calculator, there are tons of ads on this website which not only make the website look unprofessional but are also distracting when you’re using the calculator.

Click ‘Calculate’ once you have entered both the functions and the point.

The page will refresh and you will get your answer and detailed solution. Calculator-Online does a pretty solid job of representing the results with clear, huge, and highlighted fonts.

**4. Wolfram Alpha: Composite Function Calculator**

**Wolfram Alpha** is a name that you have probably heard or seen but don’t know what it actually is.

Wolfram alpha is probably the world’s largest education technology company that develops software and tools for students and the general public.

There are a lot of websites and apps that use technologies developed and powered by Wolfram Alpha.

They have plenty of tools on their website and fortunately have a really practical composite function calculator.

The interface of the calculator is very simple and clean just like you’d expect from a website of such reputation.

On the top of the calculator, the functions have been defined so you don’t get confused while entering the values. You just need to enter both functions in the input boxes.

The design of the calculator is similar to the rest of the widgets of wolfram alpha which actually makes the whole experience uniform.

The** design** of the website is minimalist but professional, you can see the subtle use of orange color all over the website which gives the website a good look.

Another really interesting thing about this website is that you can customize the UI.

On the right side of the page, you can choose the color theme of the website and the size of the output boxes. This really personalizes your whole experience.

Once you are done with the inputs, click ‘Submit’ a window will appear which will have the solution to your inputs.

**End Note **

A composite function calculator is a very simple yet effective tool that you can use for almost any composite function problem.

Even if you are good at these problems a calculator will save a lot of time for you and will also reduce the chances of error.

These Calculators just aren’t meant to be used by students, anyone with a composite function query can use them.

All of the calculators mentioned above are more than adequate to give you the correct answers, make sure you pin down the one you feel most comfortable with.
