Given below is the graph of the derivative of a function f whose domain is the set of all real numbers and which is continuous everywhere. Figure 2: Graph of f' a) From the graph, determine the following information and incorporate this information in a table: (a) the intervals on which f is increasing; (b) the intervals on which f is decreasing; (c) the relative extrema of f; (d) where the graph of f is concave upward; (e) where the graph of f is concave downward; (f) the points of inflection of the graph of f b) Sketch the graph of a function f having the properties in the table if the only zeros of f are -4, 0 and 5
