When should parentheses be used for in interval notation?

Parentheses and/or brackets are used to show whether the endpoints are excluded or included. For example, [3, 8) is the interval of real numbers between 3 and 8, including 3 and excluding 8. Note: Many authors use reversed brackets instead of parentheses. via
