Tutorial to help us answer problem 9.
The function h (t) = -16t2 + 32t + 64 is graphically represented by a parabola that opens downward. Therefore, the vertex of this parabola indicates the maximum height the object achieves (and the time at which this occurs). The vertex is found as,
We conclude that after 1 second the object reaches a maximum height of 80 feet.
