Inverse Function

  • Definition: The function obtained by switching the x- and y-variables in a function. The inverse of function f is written f^-1. Also, the new relation obtained by reversing the x- and y-values of a function is not necessarily a function itself. The new relation is only a function if the original function is one-to-one.
