Key Concepts

Compound Inequalities

Compound inequalities are expressions that involve two inequality constraints, usually resulting from the process of solving absolute value inequalities. They represent a range of values that satisfy both the lower and upper bounds simultaneously.

Graphing on a Number Line

Graphing inequalities on a number line is a visual method to represent solutions. It involves marking key points, shading the region that satisfies the inequality, and using open or closed circles to indicate whether endpoints are included in the solution set.

Absolute Value

Absolute value refers to the distance of a number from zero on the number line, regardless of direction. It is a measure of magnitude without considering sign and is often expressed with vertical bars, such as |x|, to denote this distance.

Absolute Value Inequalities

Absolute value inequalities involve expressions inside absolute value symbols and require understanding how distances compare to a given number. Solving these inequalities typically involves rewriting them as compound inequalities, expressing that the expression inside the absolute value must lie within a defined range.
