Use the information above to answer the following questions.
1. What is the relation? Write as a set of ordered pairs.
2. What is the domain of the relation?
3. What is the range of the relation?
4. The vertical line test for a function states that if any vertical line
passes through no more than one point of the graph of a relation, then
the relation is a function. Does the vertical line test indicate that this
relation is a function?
5. Repeat the experiment three times. Answer the questions for each
experiment. Can you make any generalizations about the results?
