__Inverse Function__

An Inverse Function, is a function that will undo or reverse the work that was done by an original function.

If you take a jar out of a cupboard, the inverse action would be to put the jar back in the cupcoard.

The reverse of the action that was originally done, undoing the work.

When dealing a function and its inverse, it's the same general idea.

The graph of the inverse also follows an interesting pattern.
