The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in 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 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 80 feet per second.
Part A: Write a function that can be used to describe the flight of the model rocket.

A. g(t) = -16t^2 + 80t + 80

B. g(t) = -16t^2 + 80

C. g(t) = -16t^2 + t + 80

D. g(t) = -16t^2 + 80t
