2. Estimate the area under the curve fx) x2+1 from x 0 to x 6 by using three 4 points) circumscribed (over the curve) rectangles. Answer to the nearest integer. 3. List x1, X2, x3, x4 where x, is the midpoint endpoint of the five equal intervals used to estimate (4 points) the area under the curve of f(x) between x = 0 and x-10. 02, 4, 6, 8, 10 O1,3, 5, 7,9 0,2,4,6,8 01,2,3, 4, 5 4. Write the summation to estimate the area under the curve y = 2x2 + 1 from x = 0 to x-4 using (4 points) 4 rectangles and left endpoints. 22 +1 2+1 啤22 +1) 5. If the area under the curve of f(x)-25-x2 from x =-4 to x-0 is estimated using four (4 points) approximating rectangles and left endpoints, will the estimate be an underestimate or overestimate? ○Underestimate Overestimate The area will be exact The area cannot be estimated with just four rectangles
