## Homework Statement

Determine how many integrals are required for disk, washer, and shell method.

## Homework Equations

x=3y^2 - 2 and x=y^2 from (-2,0) to (1,1) about x-axis.

## The Attempt at a Solution

Since there are no breaks or abnormalities in the graph it appears that 1 integral will solve for each to me. I have no other way of looking at this problem.

how do i know when the disk method requires more than one integral?
