1. Determine the area of the region between the two curves by integrating over the y-axis. x = y and x = 9 2 x=9 0 2 4 6 10* -2 2. Graph the equations and shade the area of the region between the curves. Determine its area by integrating over the x-axis. y= el, y = e2x -1, and x = 0 3. Graph the equations and shade the area of the region between the curves. Determine its area by integrating over the x-axis. y = e, y= e , andy = e-* 4. Graph the equations and shade the area of the region between the curves. If necessary, break the region into subregions to determine its entire area. y = x* + 9 andy = 10 + 2x over x = [-1, 3] 5. Graph the equations and shade the area of the region between the curves. Determine its area by integrating over the x-axis or y-axis, whichever seems more convenient. y+ y = x and 2y = x
