This worksheet will allow you to see domain and range in motion. On the graph below, there is a relation.
1. Make a guess. What do you think the domain would be? What would the range be?
2. Think about whether it is a function. How would you know if it is a function?
After you have answered those questions, press the play button in the bottom left corner of the graph. Watch what happens, thinking about the domain and the range of the relation.

1. What does the trail left by point B represent?
2. What does the trail left by point C represent?
3. What is the domain of the relation? (using actual numbers)
4. What is the range of the relation? (using actual numbers)
