Question

A volleyball is served from a height of 6 feet with an initial velocity of 33 feet per second. The situation is modeled using the function h=−6t2+33t+6
, where h is the height in feet and t is time in seconds.

Which of the following uses the function to correctly identify the corresponding y-values to the given x-values of 0, 1, 2, 3, and 4?

Answer 1

(0, 6), (1, 33), (2, 48), (3, 51), and (4, 42)

Calculation: h(t) = −6t^2 + 33t + 6
- h(0)=6
- h(1)=−6+33+6=33
- h(2)=−24+66+6=48
- h(3)=−54+99+6=51
- h(4)=−96+132+6=42
