mediumAn object is launched above the ground. A quadratic function f models the height above the ground, in feet, of the object x seconds after it is launched. According to the model, the object reaches its maximum height of 278 feet above the ground 5 seconds after it is launched. Which equation defines f?
A
f(x)=−16x2+278
B
f(x)=−16x2−278
C
f(x)=−16(x+5)2−278
D
f(x)=−16(x−5)2+278
