Having problems getting started on this problem. I have to find the volume of a solid bounded by y=2x^2, z=2y+1, and z= y+9
Your upper surface is y+ 9 and the lower surface is 2*y +1
If you find your point of intersection it is the line y = 8.
Y= 2x^2 is a vertical parabolic cylinder which cuts the planes creating
the region of integration in the x-yplane which is bounded by the parabola y =2X^2 and the line y = 8
