2. Remember, extreme value means mar/min value, and absolute means global. 43-68. Absolute maxima and minima Determine the location and value of the absolute extreme values of f on the given interval, if they exist. 43. f(x) = x2 - 10 on [-2, 3] 44. f(x) = (x + 1)4/3 on [-9, 7] 45. f(x) = x3 - 3x2 on [-1, 3] 46. f(x) = x4 - 4x3 + 4x2 on [-1, 3] 47. f(x) = 3x5 - 25x3 + 60x on [-2, 3] 48. f(x) = 2ex - x2 on [0, 2e] 49. f(x) = cos2 x on [0, 17 ] X 50. f(x) = (x 2 + 3 ) 2 on [-2, 2]
