- With a function of two variables, each ordered pair (x, y) in the domain of the function is mapped to a real number z. Therefore, the graph of the function f consists of ordered triples (x, y, z). The graph of a function z = f(x, y) of two variables is called a surface.

Recognize a function of two variables and identify its domain and range. Sketch a graph of a function of two variables. The definition of a function of two variables is very similar to the definition for a function of one variable.
One way to study the graph z = f(x,y) of a function of two variables is to study the graphs of the functions of one variable that are obtained by holding x or y constant. To understand this process, we need to look at the geometric significance of setting x or y equal to a constant.
The graph of a function. f. of two variables is the set of points. (x,y,z) that satisfy the equation. z=f(x,y) More specifically, for each point. (x,y) in the domain of. f. , the point. (x,y,f(x,y)) lies on the graph of. f. (Figure 15.3). A similar definition applies to relations of the form. F(x,y,z)=0. .
