14.) Let f(x)=x³, and compute the Riemann sum of fover the interval [6,7], choosing the representative points to be the midpoints of the subintervals and using the following number of subinterval (n). (Round your answer to two decimal places.) a. two subintervals of equal length (n=2) b. five subintervals of equal length (n=5) c. ten subintervals of equal length (n=10) d. Can you guess at the area of the region under the graph off on the interval [6,7]? 14.)
