  2. Chapter 1.6 Absolute Value Inequalities 9/23/2014 2:15 AM 2

  3. ABSOLUTE VALUE INEQUALITIES • Inequalities involve signs that are greater, less, and/or equal to signs. 9/23/2014 2:15 AM 3

  4. SOLVING FOR ABSOLUTE VALUE INEQUALITIES When Solving for Inequalities, remember: Less Than AND More Than OR LAMO 9/23/2014 2:15 AM 2.9: Absolute Value Inequalities 4 1-6: Absolute Value Equations

  5. And versus Or… When Solving for Inequalities, remember: Less ThAND GreatOR Than Less Than, “AND” Greater Than, “OR” 5 2-8: Absolute Value Inequalities

  6. Steps for Solving and Graphing Absolute Value Inequalities Identify whether it is an AND/OR inequality (think LAMO) Solve each inequality Check each solution and make sure there aren’t any extraneous solutions Graph appropriately on number line 9/23/2014 2:15 AM 2.9: Absolute Value Inequalities 6 1-6: Absolute Value Equations
