Hope you understand this! :DPart a) 
section Afavg=4(2)2−4(2)12−1=8section B  favg=4(2)4−4(2)34−3=32
Part b) 
The rate of change is greater between x = 3 and x = 4 than between x = 2 and x =1  because an exponential function's rate of change is increasing, unlike a linear function which has a constant rate of change.
