In Exercises 31-38, find the slope of the graph of the function at the given point: Use the derivative feature of a graphing utility to confirm your results.
Function Point
31. f(x) = 12 (2,2)
32. f(t) = 3
33. f(x) = -+3
34. y = 3x3
35. y = (4x + 1)2
36. f(x) = 3(5x - 1)2
(1,2) (0, -1) (2,14) (0, 1) (5, 0)
