Answer:
The average rate of change is 4
Step-by-step explanation:
The average rate of change of the function over the interval is given by the slope of the line that connects the points;
(5,-2) and (9,14)
The slope of a line given 2 points is calculated as;
change in y/change in x = (14- -2)/(9-5)
= 16/4
= 4
