When two inequalities are joined by the word and, the solution of the compound inequality … To use interval notation we need to first understand some of the commonly used symbols: 1. [] - brackets denote a closed interval 2. () - parenthesis denote an open interval 3. ∪ - union represents the joining together of two sets 4. ∩ - intersection represents the overlap between two sets See more A closed interval is an interval that includes the values on the end. The example above would be denoted as [12, 16] (12, 16) It is also … See more Unions and intersections are used when dealing with two or more intervals.

Now, starting from the second interval, try searching for the intersection. Two cases can arise: There exists no intersection between [l1, r1] and [l2, r2]. Possible only when r1 < l2 or r2 < l1. In such a case answer will be 0 i.e. no intersection exists.
