## Inverse Function (Definition and Examples)

For one thing, any time you solve an equation. To solve x+4 = 7, you apply the inverse function of f(x) = x+4, that is g(x) = x-4, to both sides (x+4)-4 = 7-4 . To solve 2^x = 8, the inverse function of 2^x is log2(x), so you

## How To Find The Inverse of a Function

Inverse functions are a way to undo a function. In the original function, plugging in x gives back y, but in the inverse function, plugging in y (as the input) gives back x (as the output). If a function were to contain the point ( 3,5 ), its inverse
