4-3 Patterns and Nonlinear Functions

Nonlinear Function: a function whose graph is not a line or part of a line

Problem 1: Classifying Functions as Linear or Nonlinear The area A, in square inches, of a pizza is a function of its radius r, in inches. The cost C, in dollars, of the sauce for a pizza is a function of the weight w, in ounces, of sauce used. Graph these functions shown by the tables below. Is each function linear or nonlinear?
