Question

The path of a model rocket can be represented by the equation h(t) = - t2 + 15t + 16, where h(t) is the height, in feet, of the rocket at any given time, t. What is the height of the model rocket after 3 seconds from launch?

Answer 1

Since the function represents the height of the rocket, plug in 3 for t to find out the rocket's height 3 seconds after launch.
h(3) = -(3)^2 + (15*2) + 16
