ALL
From the publication PreCalculaus for Dummies, second edition: You can use interval notation to express where a set of solutions begins and here it ends. Interval notation is a common way to express the solution set to an inequality, and it’s important because it’s how you express solution sets in calculus. Most precalculus books and some precalculus teachers now require all sets to be written in interval notation. If the endpoint of the interval isn’t included in the solution (for < or >), the interval is called an open interval. You show it on the graph with an open circle at the point and by using parentheses in notation. If the endpoint is included in the solution (for ≤ or ≥) the interval is called a closed interval, which you show on the graph with a filledin circle at the point and by using square brackets in notation. For example, the solution set 2 < x ≤ 3, rewrite this solution set as an and statement: 2 < x AND x ≤ 3. In interval notation, you write this solution as (–2, 3]. BEST! SlideRule
