# Focus on - Quadratic Models

Quadratic functions are those in the form f(x) = ax2 + bx + c, and have fascinated mathematicians for centuries. They have some fundamental properties that will explored in this unit. Probably the best known example of quadratic models are for projectiles. Anything that is thrown/launched and is subject to the laws of gravity will likely follow a quadratic path.Page under constructionTry these activities in class to...
