This worksheet will allow you to see [b]domain [/b]and [b]range[/b] in motion. On the graph below, there is a relation. [br][br][br]1. Make a guess. What do you think the domain would be? What would the range be?[br]2. Think about whether it is a function. How would you know if it is a function?[br][br]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.

This applet allows the student to type a rule, adjust the domain and then see what the range will be for that function by tracing the graph.[br]1. Type rule[br]2. Adjust the domain (sliders a & b)[br]3. Trace graph (slider n)[br]4. Turn Domain & range on.[br]5. Re-trace (if necessary)
