= Consider the function f(x) 2 - 2x² on the interval [2, 3]. Find the average or mean slope of the function on this interval, i.e. ƒ(3) – f(− 2) 3- (-2) = By the Mean Value Theorem, we know there exists a c in the open interval ( – 2, 3) such that ƒ'(c) is equal to this mean slope. For this problem, there is only one c that works. Find it.
