Tell whether a linear model or a quadratic model is appropriate for the data. If linear, tell whether the slope should be
positive or negative. If quadratic, decide whether the leading coefficient a of $x ^ { 2 }$ should be positive or negative.
-The height of a bouncing ball during one bounce, as a function of time.
A) quadratic; negative
B) linear; positive
C) linear; negative
D) quadratic; positive

Question

Quizplus · Accepted Answer

The height of a bouncing ball during one bounce, as a function of time, forms a parabolic path, which is best modeled by a quadratic equation. The leading coefficient is negative because the ball reaches a maximum height before falling back down.
