13 Suppose f(x) = (a) The rectangles in the graph on the left illustrate a left endpoint Riemann sum for f(x) on the interval 3 < x < 5. The value of this left endpoint Riemann sum is and it is an overestimate of v the area of Right the region enclosed by y = f(x), the x-axis, and the vertical lines x = 3 and x = 5. Left endpoint endpoint Riemann Riemann sum (b) The rectangles in the graph on the right illustrate a right endpoint Riemann sum for f(x) on the interval 3 < x < 5. The value of this right endpoint Riemann sum is sum and it is an underestimate of v the area of the region enclosed by y = f(x), the x-axis, and the vertical lines x = 3 and x = 5. .....
