Consider the function f (ac) = -203 - 4x2 - 4x+4 Find the average rate of change of this function on the interval (-2, 1). By the Mean Value Theorem, we know there exists a c in the open interval (-2, 1) such that f' (c) is equal to this average rate of change. Find the value of c in the interval which works Note: You can earn partial credit on this
