This question is designed to be answered without a calculator. Let f be a continuous function whose graph passes through points (4, 0), (5, 1), (8, 2), (13, 3), and (20, 4). A trapezoidal approximation of the area under the graph of y = f(x) over the interval [4, 20] with 4 subintervals is 32. 38. 42. 50.
