An inverse function goes the other way! Let us start with an example: Here we have the function f (x) = 2x+3, written as a flow diagram:

Specifically, if f is an invertible function with domain X and codomain Y, then its inverse f −1 has domain Y and image X, and the inverse of f −1 is the original function f.

Nov 13, 2025 · An inverse function basically reverses the effect of the original function. If you apply a function to a number and then apply its inverse, you get back the original number.

The inverse function is a function obtained by reversing the given function. The domain and range of the given function are changed as the range and domain of the inverse function. Let us learn more about …

In this article, we’ll discuss on what inverse functions are, how an inverse function calculator works, and why this is a very useful tool for us. We’ll also look at the examples, practical applications, and even …

To find the inverse of a function, solve the "y=" equation for x. Then swap the variables. The result is the inverse of the original function.
