A portion of the graph of the function f is shown in the figure above along with selected values for f and f', the derivative of f. The areas of the regions bounded by the graph off and the x axis are given in the figure above. The function g is defined by g(x) = [* (t)dt. -2 AB4: Evaluate L ef (x) f'(x)dx. -3
