Question

Find the average rate of change of f(x)=x^3-8x+7 from -6 to -2=? from -1 to 5=? from 5 to 7=?

Answer 1

Plug in the numbers and take the average of their difference.

So, for the first one, plug in -6 for x and solve; write down the result. Then plug in -2 for x and solve and write down the result. Then find the difference between the two (subtract the first from the second). Lastly, take the average.
