# Inverse Functions

**Inverse Functions (Question)**

For each of the function below, obtain its inverse function.

- f(x) = x + 1
- f(x) = 2/x
- f(x) = 3/(x-1)

*Guide:
*

*Function f is said to be the inverse of function g if the inverse of function f is equal to function g and vice versa.**In order to obtain the inverse function, first one need to set the function x as y then make y become the subject of the formula.**For verification purpose, one can check if ff*^{-1}(x) or f^{-1}f(x) will return to x.

**Inverse Functions (Answer)**

- f
^{-1}(x) = x-1 - f
^{-1}(x) = 2/x - f
^{-1}(x) = (3/x) + 1
