An inverse function graphing calculator will allow you to graph functions quickly and precisely, which will help you visualize how these graphs behave.

The inverse of the function y = x is y = 1/x. You can find the inverse of a function algebraically, but graphing it is a great way to visualize how an inverse function cancels its parent function out.

To find an inverse function, form an equation by giving the output value a name using a letter (such as y), then rearrange the equation to make x the subject.
