How to Find Inverse Functions?

Compute the inverse function (f^-1) of the given function by the following steps:

First, take a function f(y) having y as the variable
Now, consider that x is the function for f(y)
Then reverse the variables y and x, then the resulting function will be x
Solve the equation y for x and find the value of x

To make it convenient for you, the function inverse calculator does all these calculations for you in a fraction of a second.

Example:

Let's suppose you have a function x = y+11/13y+19. Now how to calculate the inverse of the function?

Solution:

Replace the variables y & x, to find inverse function f-1. This online inverse composite function calculator also does the same to find the inverse. Let's take a look:

y = x + 11 / 13x + 19

y (13x + 19) = x + 11

13xy + 19y - x = 11

x (13y - 1) = 11 - 19y

x = 11 - 19y / 13y - 1

Hence, the inverse function of y+11/13y+19 is 11 - 19y / 13y - 1. Here you can also verify the results by using an inverse finder. Using an online tool will save time and effort.
