Given f' (derivative) graph, sketch f graph The graph of the derivative function f' is shown below. The following questions are about the graph of the "original" function f. -4 f'(x) 3 1. Give the x-coordinate of all the local maxima of f(x). 2. State all intervals where f(x) is increasing. 3. State all intervals where f(x) is concave up. 4. State the x-coordinates of all inflection points of f(x). 5. Sketch a graph of f(x) on the graph grid above.
