Homework Statement
Here is the problem :
Find the volume of the solid generated when the area bounded between the following functions rotates along the y=4 line.
Functions: y=x^3 y=4x
Homework Equations
Functions: y=x^3 y=4x
Axis of rotation: y=4
The Attempt at a Solution
Points of intersection are x=-2,0,2
I tried making 2 integrals from -2 to 0 and 0 to 2, but I just ended up with a negative volume.
What I don't understand is that the axis of rotation crosses the area bounded these two lines make. How do I go about this? Never encountered thissituation. Maybe I am setting up the problem wrong...
