This means that the rocket was launched from a platform 112 feet above the ground.

What is an equation

An equation is an expression showing the relationship between two or more variables and number.

h is the altitude of the rocket x seconds after it was launched.

Given the function:

h(x) = -16x² + 96x + 112

The y intercept is at x = 0:

h(0) = -16(0)² + 96(0) + 112 = 112 feet

This means that the rocket was launched from a platform 112 feet above the ground.

The x intercept is at h(x) = 0:

0 = -16x² + 96x + 112

x = 7

The x intercept shows the time the rocket touches the ground was 7 seconds.

Maximum height is at h'(x) = 0

-32x + 96 = 0

x = 3

h(3) = -16(3)² + 96(3) + 112 = 256 feet

The maximum height is 256 feet.
