A relation is any set of ordered pairs. Relations and Functions tate the domain and range of each relation. For the case of a function, a well-defined function will provide the same result if the input representation is altered, but the input value will not be changed. To determine whether a given relation is a function or not, one needs first to find out the input values, then the output values.
