Consider the region bounded by the graph of y : 3:1: + 5, the m-axis, and the lines a: : 4, a: : 7. A reasonable upper bound for the area of this region is Approximate the area under the curve y : :33 | 5 from :1: : 1 to :1: : 3 using a left sum with 4 subdivisions. The area is approximately Consider the region bounded by the graph of y : 3:): + 5, the m-axis, and the lines a: : 4, :1: : 7. A reasonable lower bound for the area of this region is Use an, : 2 partitions to find an upper sum for the region under the graph of y : 2:13 i 7, above the m-axis, and between a: : 7 and :r: : 17. The upper sum for this region is I Approximate the area under the curve y : :32 from :3 : 3 to a: : 6 using a right sum with 6 subdivisions. The area is approximately I Approximate the area under the curve y : 33:3 + 5 from a: : 2 to a: : 5 using a left sum with 6 subdivisions. The area is approximately
