Ise the graph to the right for questions 4 and 5. Intersections occur at (1,3) and (4,5). 4. Let R be the region bounded by the graphs of y = 1 + 2vx and y = =(x - 1)2 + 3 as shown in the figure to the right. Write an integral expression for the area of the region with respect to the variable r. 5. Let R be the region bounded by the graphs of y = 1 + 2vx and y = = (x - 1)2 + 3 as shown in the figure to the right. Write an integral expression for the area of the region with respect to the variable y
