Question 442095: I know there is not a section, but if anyone can help with the following problem, it will be greatly appreciated.
Find the average rate of change for the function over the given interval.
y = x2 + 7x between x = 1 and x = 8

Answer by ilana(307) (Show Source): You can put this solution on YOUR website!
I believe to find the average rate of change, find y when x=8. Then find y when x=1. Then subtract the first y minus the second y, and divide by the difference of the x values, 8-1. So you subtract the 2 y values and divide by 7.
