If the problem is:  -5 < x   then  x > -5    --->    (-5, infinity)

 

Use parentheses because the -5 is not included; infinity always gets a parenthesis.

I may have misunderstood the problem; if the problem is -5 < x <= 2, then the answer is (-5, 2]

 

Round brackets if not included; square brackets if included.
