Definitions:

Composition

The process of combining two functions in such a way that the output of one function becomes the input of another.

Function

A relation between a set of inputs and a set of permissible outputs, often defined by an equation.

Inverse Function

A mathematical function that reverses the effect of another function, such that if the function f applied to an input x gives a result of y, then applying its inverse function to y gives the result x.

Function

An interrelation between a variety of inputs and a catalog of admissible outputs, with the requirement that every input is pinpointed to a unique output.
