This course begins with a brief review of what students should already know about solving equations, with a focus on analyzing and explaining the process of solving equations. Students develop a strong foundation in working with linear equations in all forms, extending solution techniques to simple equations with exponents. Students explore functions, including notation, domain and range, multiple representations, and modeling. Through the comparison of linear and exponential functions, students contrast the concepts of additive and multiplicative change. Students then apply what they have learned to linear models of data and using lines of best fit to apply regression techniques. The course closes with an exploration of integer exponents, quadratic and exponential expressions with a heavy emphasis on quadratics, and an introduction to radical functions.
