Given that has the graph shown below, use geometry to evaluate

Given that for an upper bound of is:

For the function =, use a Right Riemann sum to determine a formula that approximates the area under for in terms of , by dividing the interval into equal subintervals. Then take the limit as to calculate the exact area under the curve over . Select the correct answer.
