## Homework Statement

Hello! Could someone explain some things presented in this example: http://i.imgur.com/wVOxf.png

My friend, and I haven't been able to crack it. I get all the x-conditions right, but can't put the whole thing together into a domain. Here it's presented that xe[-2,3] due to the positive values being between them. That confuses me since i thought that when the quadratic equation has a positive index the graph of the parabola should be facing up with the opening.

Sorry for my bad math jargon(ESL)
