Answer:
option C
Step-by-step explanation:
The points (1, 5), (5, 10), (7, 8) and (8, 1) are on the graph of the function p
To find average rate of change of the function p on 5 ≤ x ≤ 8
we pick two points (5,10) and (8,1)
we apply slope formula
(5,10) is (x1,y1) and (8,1) is (x2,y2)
Plug in the values in the formula
option C is correct
