Solve the problem
-A rock is propelled upward from the top of a building 160 feet tall at an initial velocity of 200 feet per second. Give the function that describes the height of the rocket in terms of time $t$.
A) $f ( t ) = - 200 t ^ { 2 } + 16 t + 160$
B) $f ( t ) = - 16 t ^ { 2 } + 200 t + 160$
C) $f ( t ) = 16 t ^ { 2 } + 200 t + 160$
D) $f ( t ) = - 16 t ^ { 2 } + 160 t + 200$

The correct function that describes the height of the rocket in terms of time $t$ is given by the formula $f(t) = -16t^2 + vt + h$, where $v$ is the initial velocity and $h$ is the initial height. Here, $v = 200$ feet per second and $h = 160$ feet, so the correct function is $f(t) = -16t^2 + 200t + 160$.
