WebNov 16, 2024 · In this section we want to go over some of the basic ideas about functions of more than one variable. First, remember that graphs of functions of two variables, z = f (x,y) z = f ( x, y) are surfaces in three dimensional space. For example, here is the graph of z =2x2 +2y2 −4 z = 2 x 2 + 2 y 2 − 4.
