Algebra I
Algebra I is organized around the families of functions, with special emphasis on linear and quadratic functions. Students will learn to represent them in multiple ways as verbal descriptions, equations, tables, and graphs. These functions will be applied and used to model realworld situations in order to solve arising problems. Students will also learn data analysis and apply geometric properties in the algebraic realm.
