A: Find the value or values of c that satisfy the Mean Value Theorem for the function f = 1/1 x in interval [3, 1]. B: Find the value or values of c that satisfy the Rolle's Theorem for the function f = x4 x2 + 4 in interval [1, 1]. C: Find the critical points of the function f = xzex and use the Second Derivative Test, when possible, to determine the relative extrema. D: Find the critical points of the function f = x3 3x2 + 4 and use the Second Derivative Test, when possible, to determine the relative extrema
