Key Concepts

Compound Inequalities (Disjunctive)

This concept involves solving inequalities that are combined using the word 'or', which means that satisfying any one of the inequalities in the compound statement is sufficient to satisfy the entire inequality. Understanding logical disjunction is critical, as it leads to the union of solution sets rather than their intersection.

Interval Notation

Interval notation is a method of representing sets of numbers along a continuum, using parentheses and brackets to denote open and closed intervals respectively. It provides a concise way of describing the range of values that satisfy an inequality, which is essential for clearly communicating solution sets.

Graphical Representation of Inequalities

Graphing inequalities on a number line helps visualize the set of solutions by marking critical points and shading the regions that satisfy the inequality. This visual approach aids in verifying algebraic solutions and understanding the relationship between different parts of compound inequalities.
