Functions and Relations

We have discussed in class how to tell if a relation is a function.  We have used one-to-one mapping as well as ordered pairs to show relations. (REmember one person does not usually live in two houses, but more than one person can live in the same house.)  When you have a visual representation of a function, you can use the "vertical-line test".  Here is a practice activity on relations and functions.  Try it and leave me a comment to let me know what you think.
