Consider the function f(x) = - 3x2 + 5x - 2 on the closed interval [2, 5]. Find the exact value of the slope of the secant line connecting (2, f(2) ) and (5, f(5)). m By the Mean Value Theorem, there exists c in (2, 5) so that m = f' (c). Find all values of such c in (2, 5). Enter exact values. If there is more than one solution, separate them by a comma. C =
