(1 point) Consider the function f(xx) =2x3 -2x2-x-2 Find the average slope of this function on the interval (-2, 3). By the Mean Value Theorem, we know there exists a c in the open interval (-2, 3) such that f' (c) is equal to this mean slope. Find the two values of c in the interval which work, enter the smaller root first: 1 V43 3
