Answer:
The average rate of change of f(t) from t = 3 seconds to t = 5 seconds is -80 feet per second.
Step-by-step explanation:
The function that models the height of the ball is:
At t=3, 
At t=5, 
The average rate of change is simply the slope of the secant line connecting.
and 
.
The average rate of change
Answer and Explanation:
The problem provides the following information:
