Question 1 • WSFCS Math 2 CR

A soccer ball is kicked upward from a hill and then falls to the ground. The height, in feet, of the ball after t sec is modeled by the function h(t) = –16t2 + 26t +12. What is the initial height of the ball?

Answer
A
–16 ft
B
–12 ft
C
12 ft
D
22 ft

Explanation

The initial height is the height at the moment the ball is kicked, so use t = 0. Substituting gives h(0) = −16(0)² + 26(0) + 12 = 12 feet. Therefore, the initial height is 12 ft, choice C.
