1. The problem is to express a solution or set in interval notation. 2. Interval notation is a way to write subsets of the real number line using parentheses \( () \) for open intervals and brackets \( [] \) for closed intervals. 3. For example, if the solution is all numbers between 2 and 5, including 2 but not 5, it is written as \( [2,5) \). 4. If you provide the inequality or set, I can convert it to interval notation. 5. Please provide the original inequality or solution set you want in interval notation.
