Algebra I is a foundation course for all work done in upper-level mathematics at PCDS. The major goal of the course is to develop the initial concepts of linear, quadratic, rational, and exponential functions. Students use these functions to model real-world applications. Other major topics include polynomials, radicals, absolute value, inequalities, and rational expressions. The graphing calculator is used to provide graphical and numerical support for ideas that are traditionally expressed symbolically.
