Suppose a projectile is launched from a tower into the air with an initial velocity of 48 feet per second. Its
height, H, in feet, above
the ground is modeled by the function
H=-16T2 + VoT + 64

where T is the time, in second, since the projectile was
launched and Vo is the initial velocity.

A. Write a function that can be used to describe the
flight of the rocket.
