3
Essential Questions How do I solve an absolute value inequality?

4
Absolute Value Inequalities are written as two compound inequalities and solved as INTERSECTIONS or as UNIONS. If and, then (intersection) If and, then OR (union) THESE RULES ALSO APPLY FOR ≤ AND ≥.

5
If the absolute value is less than a number or expression The inequality is an INTERSECTION (and). BOTH parts must be true at the same time. The variable will fall BETWEEN two values if there is a solution. (See example 2 on p. 32 of the handout.) greater than a number or expression The inequality is a UNION (or). Either part may be true for inequality to be true. The solution will consist of all the possibilities for EITHER inequality. (See example 1 on p. 32 of the handout.)
