Definition of a Function of Two Variables

 Let  be a set of ordered pairs of real numbers. If to each ordered pair  in  there corresponds a unique real number , then  is a function of  and . The set  is the domain of , and the corresponding set of values for  is the range of . Functions of three, four, or more variables are defined similarly.
