Key Concepts

Interval Notation

Interval notation is a method for describing subsets of the real numbers by specifying an interval with its endpoints. Parentheses are used when an endpoint is not part of the solution (for strict inequalities), and brackets are used when the endpoint is included in the solution, allowing a concise representation of the set of numbers that satisfy the inequality.

Set Notation

Set notation, including set builder notation, expresses the set of all numbers that satisfy a given condition. It is used to formally define solution sets of inequalities by stating the property that elements must satisfy, which may involve conditions like being greater than or less than a specific value.

Graphing Linear Inequalities

Graphing linear inequalities involves representing the range of solutions for an inequality on a number line by shading the portion that satisfies the inequality. When the inequality is strict (using > or <), an open circle is used to denote that the endpoint is not included; when it is non-strict (using ? or ?), a closed circle is used to indicate that the endpoint is included.
