Relation or Function?

Hey!
Last class Mr.P showed us how to tell whether a graph is a function or a relation. He also showed us how to calculate a function. At first it was easy, but then Mr.P stumped us with what we thought of as an "impossible" question, but turned out it wasn't so hard after all. After that Mr.P gave us 3 worksheets, which by the way are all due next class.

REMINDER: Remember to hand in the Tables and Relations on MONDAY! Even though we don't have class on Monday, we are suppose find Mr.P and hand in the assignment.
