Module 10HW: Problem 3(1 point)Suppose f(x)=x211.a. The rectangles in the graph on the left illustrate a left endpoint Riemann sum for f(x)on the interval 3x5. The value of this left endpoint Riemann sum is and itisan underestimate of the area of the region enclosed byy=f(x), the x-axis, and the vertical lines x=3 and x=5.b. The rectangles in the graph on the right illustrate a right endpoint Riemann sum for f(x)on the interval 3x5. The value of this right endpoint Riemann sum is and itisan overestimate of the area of the region enclosed byy=f(x), the x-axis, and the vertical lines x=3 and x=5.You have attempted this problem 7 times.
