Consider the following curves Carty =1 C2:p' +y'=9 C3 : y= x+1 CA : y =0 that are shown in the figure below. 2- R /-1 21 Ca C1 Define the following regions, also shown in the figure above. . Q is the region bounded by Cs on the left, C on the right, and Ca below. . R is the region enclosed by all four curves: above Ci and Ca, below Ca and C2. (a) Use a Riemann Sum to approximate the area of the region Q. Use any rule we studied in class, and n = 4 subintervals. (b) Set up integral(s) to compute the area of the region R. (c) Set up integral(s) to compute the volume of the solid obtained by rotating @ around C4. You may use Desmos or other graphing software to help you solve for points of intersection (attach a screenshot if you do, and cite the software used). You do not need to evaluate the integrals in (b) and (c), but your solution should clearly indicate how you are breaking up the region (if you are), and explain how the integrals were obtained
