Solution

points on graph are (0,0),(8,16),(16,26),(24,32),(32,32).(36,32)

average rate of change from  (a,b),(c,d) =[(d-b)/(c-a)]

average rate of change from  (0,0) to (8,16) =[16-8]/[8-0]= 8/8=1

average rate of change from  (8,16)to (16,26) =[26-16]/[16-8]= 10/8=5/4=1.25

average rate of change from  (16,26) to (24,32) =[32-26]/[24-16]=6/8=0.75

average rate of change from  (24,32) to (32,32) =[32-32]/[32-24]= 0

average rate of change from  (32,32) to (36,32) =[32-32]/[36-32]= 0
