For the second question, IF I READ IT RIGHT, I think it is the third answer.

retireed · Answer

I think so.  I think they want to know the area where the three inequalities intersect.

Look at the attached file and see if you agree.

retireed · Answer

The third question is very odd.  I must not be understanding the question, since to me none of the answer look correct.  I need to study it some more.

I still don't understand the third question.  Sorry your on your own for that one.
