Consider the function [math] on the interval [math].
(A) Find the average or mean slope of the function on this interval.

Average Slope =
(B) By the Mean Value Theorem, we know there exists a [math] in the open interval [math] such that [math] is equal to this mean slope. Find all values of [math] that work and list them (separated by commas) in the box below.
