Question 10 its om Consider the function f(x) = 13 - 5x on the closed interval [ - 1, 3]. Find the exact value of the slope of the secant line connecting ( - 1, f( - 1)) and (3, f(3)). ink m = utoring By the Mean Value Theorem, there exists c in ( - 1, 3) so that m = f' (c). Find all values of such c in ( - 1, 3). Enter exact values. If there is more than one solution, separate them by a comma. C = port Submit Question 8
