Problem #10: The derivative of a function f(x) is given below. Find the critical numbers of f(x) and classify each as a corresponding relative maximum (max), relative minimum (min), or neither. f' (x) = ( 4-x)(9 -x)3 (x2+10)4 (A) x = 4, min; x = 9. max (B) x = 4, max; x = 9, neither (C) x = 4, max; x = 9, min (D) x = 4, neither; x = 9, max (E) x = 4, neither; x = 9, min (F) x = 4, min; x = 9, min (G) x = 4, min; x = 9. neither (H) x = 4, max; x = 9, max Problem #10: Select V Just Save Submit Problem # 10 for Grading X Problem #10 Attempt # 1 Attempt =2 Attempt =3 Your Answer: Your Mark: Problem #11: Determine all values of x where the following function is concave up. f (x) = Tax+ + 3x JX - 15x + 11 (A) -10 1 (E) x 0 (F)x> -9 (G)x > -10 (H) x
