1. Warm Up
Find a function that models the relationship between the number of sides and the number of diagonals of a polygon.
Use the function to find the number of diagonals of a dodecagon (a 12-sided polygon)
Hint: Below are some illustrations to get you started. Begin by drawing more polygons and completing the table started for you.

2. Equivalent Quadratic Forms

3. Goal
Today we are only dealing with quadratics (2nd-degree polynomials).
We are going to review the general form, as well as learn about two new forms of quadratic functions
All different ways to write the same thing.
