FUNCTION

Function

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x2. The output of a function f corresponding to an input x is denoted by f . In this example, if the input is −3, then the output is 9, and we may write f = 9. The input variable are sometimes referred to as the argument of the function.
