Previous Problem Problem List Next Problem (A) Estimate the area above the a-axis and under the graph of f (ze) - 3x3 + 4 from z = -1 to a = 4, first using 5 approximationg rectangles and right endpoints, and then improving your estimate using 10 approximationg rectangles and right endpoints. Area of 5 Rectangles = Area of 10 Rectangles = B) Repeat part (A) using left endpoints. Area of 5 Rectangles = Area of 10 Rectangles = (C) Repeat part (A) using midpoints.
