1. 5.4 Solving Compound Inequalities Objective: Solve compound inequalities containing the word and or or and graph their solution set.

2. Compound Inequality • Two or more inequalities that are connected by the words and or or

3. Intersection • The graph of a compound inequality containing the word and; the solution is the set of elements common to both inequalities. • ****TRUE ONLY IF BOTH INEQUALITIES ARE TRUE****

4. Union • The graph of a compound inequality containing or; the solution is a solution of either inequality, not necessarily both • **** TRUE IF AT LEAST ONE OF THE INEQUALITIES IS TRUE****

5. Solving Compound Inequalities • Separate the compound inequality into 2 inequalities • –2 x-3 < 4 becomes • -2 x-3 and x-3 < 4 • 2) Solve each inequality • 4) Find where the Graphs Intersect (and) or Union (or)
