Which phrase describes a nonlinear function

a The area of a circle as a function of the radius
b the perimeter of a square as a function of the side length
c the cost of gasoline as a function of the number of gallons purchased
d distance traveled by a car moving at constant speed as a function of time



Answer :

Nonlinear means not in a straight line if you graph it.

The answer would be C because the number of gallons of gasoline purchased varies.
