Question

A projectile is shot into the air following the path, h(x) = 3x2 - 12x + 5. At what time, value of x, will it reach a maximum

height?

Answer 1

never

Explanation:

The given path equation describes a path that starts at h(0) = 5, decreases to h(2) = -7, then increases without bound.

Assuming the projectile stops moving when h(x) = 0, it starts at its maximum height at ...

x = 0
