Consider the function rs) = 32:3 4:: on the closed interval [2, 7]. Find the exact value of the slope of the secant line connecting (2, K2\" and [7, HT\". By the .Mean Value Theorem, there exists c in (2, 7) so that m = f '(c). Find all values of such c in (2, 7). Enter exact values. If there is more than one solution, separate them by a comma
