Answer:
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.
Average speed is given by [Total Distance] ÷ [Total Time]
Average speed =

km/hour
Answer:
-3 < x < 1, This is the domain
