**Course: Algebra 2 (and Algebra 2 GT)**

Building on their work with linear, quadratic, and exponential functions, students extend their repertoire of functions to begin to explore other function families. Students review key features (domain, range, relative extrema, intervals increasing/decreasing, end behavior, continuity) of function graphs and describe features when provided with a function or a graph. Students begin to fit real-world data to potential function families and begin to explore inverses graphically.

The Mathematical Practice Standards apply throughout this course, and, together with the content standards, prescribe that students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make sense of problem situations. This unit serves as an introduction to function families and modeling with functions and lays the groundwork for deeper study of individual function families.
