Inverse function in discrete mathematics. Be sure to write the final answer in the form f 1 y. Y x 2 y x f 1 x x. F 1 y x y f x so write y f x using the function definition of f x. That is express x in terms of y.

Here we have f x x 2 and f 1 x x. Therefore we can find the inverse function f 1 by following these steps. If we want to find the inverse of the image of f x x 2 then. Mathbb r to mathbb r.
