In exercises 29–34, graph the function and identify intervals on which the function is increasing, decreasing, or constant. 30. ƒ1x2 = 0 x + 1 0 + 0 x - 1 0 - 3 32. h1x2 = 0.51x + 222 - 1 34. ƒ1x2 = x3 - x2 - 2x in exercises 41– 46, use a grapher to find all local maxima and minima and the values of x where they occur. give values rounded to two decimal places. 42. g1x2 = x3 - 4x + 1 44. ƒ1x2 = 1x + 321x - 122 in exercises 47–54, state whether the function is odd, even, or neither. 48. g1x2 = x3 50. g1x2 = 3/ 1 + x2 52. ƒ1x2 = x3 + 0.04x^2 + 3
