Double Integral over General Region - Set up 2 ways

Set up, but do not evaluate, the double integral over a triangular regions. First set up to integrate with respect to y and then with respect to x. Second set up is to integrate with respect to x and then with respect to y.
When integrating with respect to x first, it's necessary to split the domain into two separate regions, each with its own double integral, and then add them together.
