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: ...

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.

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) ...

Sketch derived, inverse or other related functions using graph translations. Complete the square and find composite functions for Higher Maths.

Just as any number has an inverse, many functions also have inverses. For example, the inverse of 5 is ⅕. The inverse of the function y = x is y = 1/x.
