mediumAn 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?
A
f(t)=−16(t−3.8)2+231.04
B
f(t)=16(t+3.8)2+231.04
C
f(t)=−16(t+3.8)2+231.04
D
f(t)=16(t−3.8)2+231.04
