In this course, students are provided with a foundational development of the concepts of variables, expressions, and equations using symbolic algebra. The scope of this course is limited to linear expressions and functions as well as some work with exponential expressions and functions. Instruction focuses on the following areas: (1) formulating and reasoning about expressions and equations, including modeling an association in bivariate data with a linear equation and solving linear equations and systems of linear equations; and (2) understanding the concept of a function and using functions to describe quantitative relationships. Placement in this course must be approved by the Math Director.
