Pre-Cal answer:

This is a quadratic function (y = ax^2 + bx +c) so to find the max value, find the vertex.

t = -b/2a = -30/(2)(-16) = 0.9375s (time of max h)

h(0.9375) = -16(0.9375)^2 +30(0.9375) + 6 = 20.06ft

Calculus answer:

h'(t) = -32t +30

-32t +30 = 0

t = 0.9375s (critical pt)

h(0.9375) = -16(0.9375)^2 +30(0.9375) + 6 = 20.06ft
