This course has been designed to support the study of equations, functions, graphs, modeling, and problem solving. Linear, quadratic, exponential, and logarithmic equations in one variable are applied to a variety of problems, which concern real-world situations. Systems of linear equations in two variables are supported in conjunction with their use in problem solving. The concepts of functions and graphing are studied as essential tools for interpreting functions of one variable. Linear, quadratic, exponential, polynomial and logarithmic functions are emphasized and used to model a variety of real-world situations.
