**1. Homework Statement**

I must divide a region into integrals to find the area. I'm not sure how to write it. Do I need to setup 3 separate integrals or can I just multiply the second one by 2 since I know the parabola is symmetric to the x-axis and the area bounded by the parabola and the dotted line above is equal to that which is below. What's the correct convention to set this up? Thanks again, this forum has been very helpful.
