1. Lesson 6-4B Objective: Solve compound inequalities with OR. Two or more combined Union

2. In the first box of your notes: The word “OR” means: Union Everything put together For example, where is the union of Riley and 152 nd ? Riley St. 152 nd Ave. The union is everything on Riley combined with everything on 152 nd

3. Another example (put in 2 nd box of notes): Another example (put in 2 nd box of notes): The union of compound inequalities looks like this: x < 6 or x ≥ -2 0 6-2 x < 6 x ≥ -2 What is in one or the other graph? In other words, what is their union ? All Reals!

4. Your Turn: Graph the solution to x < 6 or x < 3 0 63 What is in one or the other graph? In other words, what is their union ? x < 6 x < 3 x < 6 !

5. Example 4-3a Graph: Now, try this:

6. Example 4-4a Then graph the solution set. or

7. Example 4-4a Graph Answer: The solution set is

8. Example 4-4b Then graph the solution set. Answer: Last One!
