The function () = − 16 represents the height of an object, g, in feet above the ground in 2 + + ℎ relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet. A model rocket is launched off the ground at an initial velocity of 128 feet per second.

Part A: Write a function that can be used to describe the flight of the model rocket.
A) () = − 16 2 + 128 + 128
B) () = − 16 2 + + 128
C) () = − 16 2 + 128
D) () = − 16 2 + 128

Part B: What domain makes sense for the function in this context?
A) 0 ≤ ≤ 8
B) 0 ≤ ≤ 100
C) All real numbers
D) All positive numbers
