## anonymous one year ago function f(x) = x^4 - 2x^3 What is the average rate of change from x = -1 to x = 2?

1. campbell_st

so the average rate of change is $avg ~rate~of ~change ~ = \frac{f(-1) - f(2)}{-1 -2}$

2. campbell_st

you are basically finding the slope between the points (-1, f(-1)) and (2, f(2))

thank you ~
