Let  f(x)=x^2+3x+2 .

What is the average rate of change of f(x) from 3 to 6?

 

f(3)  =  (3)^2 + 3(3) + 2  =   20

f(6)  = (6)^2 + 3(6) + 2  = 56

 

Avg rate of change from 3 to 6  =  [ f(6) - f(3) ]             56 - 20          36

                                                     ___________  =     _______  =    ___   =  12

                                                          6  -   3                     3                 3

 

2)  Avg rate of change  from - 2 to 2  =  [ 9 - 25 ]           -16

                                                               _______ =       ____  =  - 4

                                                                 2 - (-2)               4
