In Problems 33-48, find the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema. 46. f(x) = (x + 2) et In Problems 49-56, find the intervals on which f(x) is increasing and the intervals on which f(x) is decreasing. Then sketch the graph. Add horizontal tangent lines. 54. f(x) = x³ + 3x² + 3x
