What is the function
1) -3 <_ x < 1
2) -3 < x <_ 1
3) -4 < y <_ 2
4) -4 <_ y < 2

As the point (-3,-4) has an open circle on it , So we do not include this point in our answers .
while the other point (1,2) has a closed circle on it , so we include it in our answer .
So the two answers should be
[tex] -3<x\leq 1 [/tex] and [tex] -4<y\leq 2 [/tex]
i.e. 2) and 3) are the correct answers
