Prompt

An object is launched into the air from ground level. According to a quadratic model,

3.8

seconds after the object is launched, it reaches its maximum height of

231.04

feet above ground level. Which equation represents this model, where

f (t)

is the object's height, in feet, above ground level

t

seconds after it was launched?

f (t) = - 16 (t - 3.8)^{2} + 231.04

f (t) = 16 (t + 3.8)^{2} + 231.04

f (t) = - 16 (t + 3.8)^{2} + 231.04

f (t) = 16 (t - 3.8)^{2} + 231.04
