Answer 1

A

Explanation:

The projectile motion of Jenny's dive can be represented by
`-at^2 + v_0t + h_0` where a is acceleration, v_0 is velocity, t is time, and h_0 is initial height.

Jenny's vertical height above the water is represented by
`-16x^2+12x+10`. 10 is h_0 and is Jenny's initial height.
