Problem 6. (1 point) (incorrect) Use six rectangles to find an estimate of each type for the area under the given graph of / from x = 0 to x = 12. Problem 4. (1 point) Estimate / x using right endpoints for n = 3 approximationg rectangles. dix is approximately 1. Take the sample points from the left-endpoints. Answer: L6 = Answer(s) submitred: 2. Is your estimate L an underestimate or overestimate of the (incorrect) true area? Choose one . Underestimate . Overestimate 3. Take the sample points from the right-endpoints. Answer: R6 = Problem 5. (1 point 4. Is your estimate Ro an underestimate or overestimate of the true area? Estimate / 4 -x3 dx using midpoints for n = 4 approximationg Choose one rectangles. Underestimate . Overestimate 4 -x x is approximately 5. Take the sample points from the midpoints. Answer(s) submitted: Answer: M6 = (incorrect) Note: You can click on the graph to enlarge the image.
