To find the inverse of the function
, the first step is to replace f(x) with "y":

The second step is to solve for the variable "x":

The third step is to interchange the variables, then:

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:
