The height of a falling object can be modeled by the equation h=-16t" + vt +h, where

V is the initial velocity in feet per second, t is time in seconds, and h, is the initial height

in feet. Is the function linear or nonlinear, and why?

a. It is linear, because the object falls in a straight line.

b. It is linear, because the object falls at a constant speed.

c. It is nonlinear, because the object does not fall in a straight line.

d. It is nonlinear, because the object does not fall at a constant speed.
