Thursday we examine completed investigation 3.2. We examined the quadratic patterns of square, rectangular, and triangular numbers but applied them to a different scenario, hand shakes.
Homework: page 55 (9-11)
Friday we reexamined the hand shake situations from Thursday and we worked on creating equations, tables and graphs for each one. We discussed the patterns we see for quadratic functions in the table, graph, and equation.
Due Wednesday, February 22: Remember to make quiz corrections. If you need extra points and you have below an 85% on your quiz (after corrections) complete the worksheet at the following link https://drive.google.com/file/d/0B9_EAUW_J80vOE1UOERjck5QYW8/view?usp=sharing.
