Every operation has an opposite. With functions the opposite is called the inverse function. It undoes the function and returns you to the initial input.
There is a simple process to follow to find the inverse of any function which we look at in this video.
1) Start by writing the function as y=
2) Switch the x and y's around to get x =
3) Rearrange to make y the subject once more
4) You've found the inverse, so rewrite it as f^-1(x)
