The document discusses modeling quadratic equations by sketching parabolas based on real world scenarios. It includes examples of sketching the path of a jackrabbit jumping over a fence, the path of a soccer ball kicked to a height of 100 feet at a distance of 150 feet, and the cross sectional view of a skatepark U-Dip feature. The document also covers rewriting quadratic equations from standard form into graphing form in order to sketch the graph.
