7. The area of the region that lies to the right of the y-axis and to the left of the parabola x = 2y.- y (the shaded region in the figure) is given by the integral f (2y - y) dy. (Turn your head clockwise and think of the region as lying below the curve x = 2y - y from y = 0 to y = 2.) Find the area of the region. 2 x= 2y = y 0
