Teacher presentation materials. Unit: Alg1.6 Introduction to Quadratic Functions (Algebra 1). Alg1.6 Introduction to Quadratic Functions In this unit, students study quadratic functions systematically. They look at patterns which grow quadratically and contrast them with linear and exponential growth. Then they examine other quadratic relationships via tables, graphs, and equations, gaining appreciation for some of the special features of quadratic functions and the situations they represent. They analyze equivalent quadratic expressions and how these expressions help to reveal important behavior of the associated quadratic function and its graph. They gain an appreciation for the fact
