Domain and Range Tracing

This worksheet will allow you to see [b]domain [/b]and [b]range[/b] 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 [b]in the bottom left corner of the graph[/b]. 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)
