2. The graph of f '(x) is shown. Use the graph to answer the following: For which values of x, is a) x) increasing? Comm [1] b) f(x) concave up? Justify. Comm [2] 0) State the x-coordinates of any possible local extrema. State whether they are local max or local minimum points. Justify. T/I [2] (1) State the coordinates of any points of inection. Justify. T/I [2] c) Using the graph of f '(x), and the fact that f(x) has a horizontal asymptote at y = 0 which it never crosses, make a possible sketch of f(x). K/U [3]
