Given the graph below, use 5 rectangles to find an estimate for the area under the graph from x = 0 to x = 10. Find the lower and upper estimates for the area. 104 8-5 6+ 4- 24 0 (a) Lower = 36.4 and Upper = 43.4 (b) Lower = 38.4 and Upper = 42.4 (c) Lower = 34.4 and Upper = 46.4 (d) Lower = 32.4 and Upper = 48.4 (e) Lower = 31.4 and Upper = 47.4
