1. 4.22 Domain and Range from a Graph Nov. 10 and 11

2. Bell Ringer In your own words, describe the difference between Continuous and Discrete functions.

3. Review Domain: Refers to the x-values that are represented in a problem. Read from left to right. Range: Refers to the y-values that are represented in a graph. Read from the bottom to the top.

4. Review Discrete: When you have to lift up your pencil to trace the graph. We list all our x-values in brackets { } for our domain and all our y-values in brackets { } for our range. Ex. Domain:_________ Range:__________ Function?________

5. Review Continuous: When you can trace the graph without lifting your pencil. We use interval notation to write the domain and range. Ex 1: Continuous with two end points. Domain:_________ Range: __________ Function?________

6. Review Ex 2: Continuous graph with only one end point and continues forever in the other direction. Domain: _________ Range: __________ Function? ________

7. Review Ex 3: Continuous with no endpoints. Two arrows in both directions. Domain: _________ Range: __________ Function? _______

8. Match Activity! Pull out a half sheet of paper. Put your name and date on the top. Label it Domain and Range Activity and number your paper 1-24. Working with your partner, you are going to match the graph to the given domain and range.
