Functions and their representations are used to model and analyze real-world applications and quantitative relationships. In this unit, students develop an understanding of the concepts that linear functions involve a constant rate of change and that equations that represent linear functions have an infinite number of solutions. These concepts provide a foundation for further study of linear equations and other functions in subsequent units and courses.
The purpose of this unit is to create a bridge between students’ understanding of equations in one variable and equations in two variables. The focus of instruction is on using algebra as a tool for representing and analyzing relationships between quantities that change. Equations in two variables represent relationships between two quantities. Students investigate how numeric, graphic, and algebraic representations of relations and functions are related. Each representation of a function further clarifies the characteristics of that function. Students are also introduced to function notation. This notation will be used throughout the course.
Unit 2 is typically a three-week unit taught in October
