Key Concepts

Inequalities

Inequalities are mathematical expressions that show the relationship between two values when they are not equal. They use symbols such as '≤' (less than or equal to) and '≥' (greater than or equal to) to indicate the range of values that satisfy the condition. Understanding how to interpret and manipulate inequalities is essential for solving problems that involve ranges of numbers.

Interval Notation

Interval notation is a mathematical notation used to represent a set of numbers between two endpoints. It uses brackets '[ ]' to include endpoints and parentheses '( )' to exclude them. For example, the interval [6, ∞) represents all numbers greater than or equal to 6. Familiarity with interval notation is crucial for translating inequalities into a concise format.

Graphing Inequalities

Graphing inequalities involves representing the solutions of an inequality on a number line. A solid dot is used for '≤' or '≥' to indicate that the endpoint is included, while an open dot is used for '<' or '>'. This visual representation helps in understanding the range of values that satisfy the inequality, making it easier to match with interval notation.
