## 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 # 01: Calculate the inverse of the functions x = y+11/13y+19? Solution: Replace the variables y & x, to find inverse function f-1 with inverse calculator with steps:

$$y = x + 11 / 13x + 19$$

$$y (13x + 19) = x + 11$$

$$13xy + 19y – x = 11$$

$$x (13y – 1) = 11 – 19y$$

$$x = 11 – 19y / 13y – 1$$

Hence, the inverse function of y+11/13y+19 is 11 – 19y / 13y – 1. Here you can also verify the results by using this best find f^-1(x) calculator.
