Question

Given H = f(t) where H is the height in meters of an object and t is the time in

seconds since it was launched, which of the following is the best interpretation of f(2) =18?
A. The object travels 2 meters for every 18 seconds.
B. 18 seconds after the object is launched it is traveling 2 meters per second.
C. The object is 36 meters in the air.
D. 2 seconds after the object is launched it is 18 meters in the air.
E. The object travels 18 meters for every 2 seconds.
F. 2 seconds after the object is launched it is traveling 18 meters per second.
G. 18 seconds after the object is launch it is 2 meters in the air.

Answer 1

D

Explanation:

Well, since t = time in air, we already know that it traveled 2 seconds.

H = height in meters, and H = 18

So, after 2 seconds the object is 18m in the air

So, option D
