Question

How do you find the average rate of change for the function `f(x) = 2x^2 - 3x` on the indicated intervals [-1,2]?

Answer 1

Simply find the slope of the line passing through the endpoints of the interval.

Explanation:

average rate of change = `(f(2)-f(-1)]/(2-(-1))`

= `(2-5)/(2+1)=-3/3=-1`
