Answer:
b) 1
Explanation:
The average rate of change on an interval is given by the rise on the interval divided by the run (the width of the interval). Here, the end points are ...
(5, -3) and (8, 0)
The rise is 0-(-3) = 3. The run is 8 -5 = 3. The ratio of rise to run is 3/3 = 1.
The average rate of change on [5, 8] is 1.
