a
13. The height of a ball thrown out of a
window 48 feet above the ground is
modeled by f(x) = (-8x-8)(2x - 6),
shown on the graph below, where x is
the number of seconds after the ball is
thrown and f(x) is the height of the ball
in feet.

Answer 1

The vertex is 64 feet after 1 second and the ball stays in air for 3 seconds.

What is an equation?
