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.

Linear Relationships

We are currently working with linear relationships represented by arithmetic sequences.  We have generated closed and recursive formulas for sequences as well as using these formulas to generate sequences.  Here is a neat game to provide practice in identifying linear relationships.  Play the game and leave a comment letting me know what you think.
