Estimate the area of the region bounded by the graph of f(x) = x + 8 and the x-axis on [0,8] in the following ways. a. Divide [0,8] into n = 4 subintervals and approximate the area of the region using a left Riemann sum. Illustrate the solution geometrically. b. Divide [0,8] into n = 4 subintervals and approximate the area of the region using a midpoint Riemann sum. Illustrate the solution geometrically c. Divide [0,8] into n = 4 subintervals and approximate the area of the region using a right Riemann sum. Illustrate the solution geometrically. . The left Riemann sum is (Type an integer or decimal rounded to three decimal places as needed.) CI ok Ask my instructor Q Search pause 12 19 $ 10 & 5 O 3 P E R T H K F G V B N M
