1. 1-4 Solving Inequalities
Objectives:
Solve inequalities.
Solve compound inequalities.
Identify conjunctions and disjunctions.
Graph solutions to inequalities.

2. Definition
Compound Inequalities – a pair of inequalities joined by and or or.

5. Compound Inequalities
Conjunction
1. An “and” inequality problem.
2. The variable is in the middle of the
two inequality symbols.
3. The graphs of a conjunction “connect” towards each other.
4. The solutions of a conjunction problem will make both inequality problems true.

6. 4 EXAMPLE

7. Disjunction
1. An “or” inequality problem. 2. The problem has the word or in it. The graphs of the solutions will go in opposite directions or one single direction. 3. Only one of the inequality problems have to be true for a disjunction problem.
