Amir stands on a balcony and throws a ball to his dog, who is at ground level.

The ball's height (in meters above the ground), x seconds after Amir threw it, is modeled by

h(x)=-(x+1)(x-7)

What is the maximum height that the ball will reach?

16 meters

Step-by-step explanation:

The height function is given by:

The value of x, in seconds, for which the derivate of the height function is zero, is the time at which the maximum height occurs:

For x = 3 seconds, the height is:

The maximum height that the ball will reach is 16 meters.
