For example, for a function that multiplies by 3 and subtracts one, the inverse function is add one and then divide by 3. A function machine can help you to check your steps are in the correct order: ...

The second way to graph the inverse function is algebraic. Start with the original equation’s function, swap x and y, and then solve. For example: f (x) = 5x +10 (original function of x) ...

Inverse graphing calculators help higher-level math students, such as those in advanced algebra and pre-calculus, visualize functions and their inverses to learn how the graphs behave.
