3) Two Determine the area of the region enclosed by x = ly - 3 and y = x - 1. Set up the integral expression and calculate the area showing all your work. Include a sketch of the region. 4) Two parabolas are graphed, and the region enclosed between them is rotated around y = 1 to generate a 3D object. Calculate the volume of the shape by creating the expression and using your calculator to find the volume. y = 9- x2 y = x+1
