Quadratic Equation Project

Hello all,

As part of your assessment from our Quadratics Unit, you are required to create a poster that describes the various parts of a quadratic and how you can use these parts to create a graph of the quadratic. Additionally, you are required to find examples of parabolas in everyday life.

Attached here is the project description and rubric, you received your equation in class: Quadratic Equation Project

I have also attached pictures of the list of assigned equations for each class.
