Student Notes For Functions - Algebra 2 Honors or Pre-Calculus AB

"Hey guys! Today we are going to put the FUN in functions!" I exclaim, cheerily at 8:30 this morning, even before the coffee has set in.
"Lies, all lies!" says student B, making me giggle, as I know she's saying that but she's truly a motivated student. I am very lucky to be teaching this Algebra 2 Honors class.

Have any good ideas for teaching functions? Send them my way!
