8.6 Area-Multiple Intersections Calculus-Calculator Allowed Mastery Check #2 The given functions create boundaries for multiple regions. 1. y=2x--7x, y=x+3x a. Find the x-values of the points of intersection, and label them from smallest to largest as A, B, and C. A= B C Name: Date: Period: 2. y=7x-x2,y=12,x=0 a. Find the x-values of the points of intersection, and label them from smallest to largest as A, and B. A = B C = b. Set up integrals b. Set up integrals 3. The figure shows the graph of y = 2 sin(x), and the line y = 1, for 0 x . Write a set of integrals that represents the sum of all the areas of the shaded regions. Use exact values for your boundaries, not rounded decimals. 2+ 1- R T B2 5+ TC 4 2
