Jist want to question #32 and #38

For the following exercises, find the average rate of change of each function on the interval specified. 28. f (x) - x2 on [1, 5] 29. h (x) - 5 - 2x2 on [ 2, 4] 30. q (20) - 23 on [ 4, 2] 31. g (x) - 3x3 - 1 on [-3, 3] 32. y = - on [1, 3] 33. P (t ) - ( 4 ) (:+1) of on [-3, 1] 34. k (t) = 6t2 + # on [-1, 3] Technology For the following exercises, use a graphing utility to estimate the local extrema of each function and to estimate the intervals on which the function is increasing and decreasing. 35. f (ac) = 24 - 4203 +5 36. h (ac) = 25 + 5xc4 + 1023 + 10x2 - 1 37. g (t) =tvt +3 38. k (t) = 3t 3 - t 12
