Problems 9-16 involve estimating the area under the curves in Figures A-D from x = 1 to x = 4. For each figure, divide the interval [1,4] into three equal subintervals.
a. Draw in left and right rectangles for Figures C and D.
12b. Using the results of Problem 10, compute L3 and R3 for Figure C and for Figure D
c. Replace the question marks with L3 and R3as appropriate. Explain your choice.

d. Compute error bounds for L3 and R3found in Problem 12 for both figures.
