How can I restrict the domain and range to the first quadrant?
Answered
I have created an unbound polygon of constraints, but since the solution set must be positive I would like to shade only the first quadrant. (I've attached my file as well as the image that I'm trying to translate.) Thank you in advance to the community for your help!
The same question 
and this:
Preferences - Graphics --> xAxis : Positive direction only
Preferences - Graphics --> yAxis : Positive direction only
Thank you! Solved!
