Answer:
A function is a relation between a set of inputs and a set of permissible outputs, provided that each input is related to exactly one output. An example is the function that relates each real number [Math Processing Error] to its square [Math Processing Error]. The output of a function [Math Processing Error] corresponding to an input [Math Processing Error] is denoted by [Math Processing Error] (read “f of x“). In this example, if the input is [Math Processing Error], then the output is 9, and we may write [Math Processing Error]. The input variable (s) are sometimes referred to as the argument(s) of the function.
