If is the inverse function of , then . In this Demonstration you can choose two functions and . The graphs of and are drawn with red and blue dashes. Choose the composition or . The graph of the composition is drawn as a solid green curve. If it is the line , the functions are inverses of each other. If the solid curve is only partly the same as the line , the domain of the functions has to be restricted.
