Usually you would write this as {x: -3 < x <= 5} and then then interval notation would be (-3, 5].

It's (-3, 5]. The smaller value (taking the sign into account) must be on the left. The parentheses ( and ) correspond to strict inequalities < and >, while square brackets [ and ] correspond to non-strict inequalities and .

so if something has the infinite symbol '-' <------ similar to that than that symbol is moved to the right?
