$$2\le x\le3$$  

$$-2\le x\le3$$  

$$-2\ge x\le-3$$  

The inequality has no solution

$$x+3>1\ \&\ x+3>-1$$  

$$x+3\ >1\ \&\ x+3\ <-1$$  

$$x+3\ge\pm1$$  

None of the answers are correct

0 < x < 2 or 6 < x < 8

0 < x <-2 or 6 < x <8

$$x\in\infty$$  

No real solution

$$x\in R\ ,\ y\ >0$$  

$$x\in R\ ,\ y\ \in R$$  

$$x>0\ ,\ y\ \in R$$  

$$x\ >0\ ,\ y\ \ >0$$
