Abstract

A function f is a mapping which takes each element of the domain D into an element of the range S. We write f: D → S. If the domain D consists of ordered pairs of numbers, then we have a function on R e or a function of two variables. We employ the notation

z=f(x,y) or f:(x,y) → S

to indicate a typical function on R 2 when the elements of the range are real numbers (elements of R’).
