Solve the problem.A rocket is shot straight up in the air from the ground at a rate of 79 feet per second. The rocket is tracked by a range finder that is 411 feet from the launch pad. Let d represent the distance from the rocket to the range finder and t represent the time, in seconds, since "blastoff". Express d as a function of t.
A. d(t) = 
B. d(t) = 
C. d(t) = 411 + 79t2
D. d(t) = 4112 + (79t)2
