A rock is thrown upward from the edge of a cliff. The rock follows the equation below:
S=24+64t-16t^2
What is the greatest height above the ground that this rock will go?
---------------
Max height is at the vertex of the parabola.
Vertex is on the AOS, Axis of Symmetry, t = -b/2a = -64/-32
@ t = 2, S = 24 + 128 - 64
S = 88 ft
