Answer:
Relative minimum : Â -36
Relative maximum : Â 64
The rate of change is 336 greater
Step-by-step explanation:
Relative minimum are the minimum values  in the interval
Looking at the graph, we find the lowest point in the interval
Relative minimum : (-3, -36) and (3,-36) Â y value -36
Looking at the graph, we find the highest point in the interval
Relative maximum : (0,64) Â y value 64
Average rate of change = f(x2) - f(x1)
                     ---------------
                      x2 - x1
                   Â
                     f(7) - f(5)   1469 - 549    920
                    ------------- = ---------------  = ------- = 460
                       7-5        7-5         2
                     f(4) - f(2)   287 - 39     248
                    ------------- = ---------------  = ------- = 124
                       4-2        4-2         2
We need to subtract
460-124
336
