Algebra 2

Powers, Roots, and Radicals introduces types of equations and functions beyond linear, quadratic, and exponential functions you studied in earlier math courses. Explore properties of square roots and other radicals, which makes Simplifying Radical Expressions possible. Practice Adding and Subtracting Rational Expressions with Unlike Radicands, and learn what it means to take the Function of a Function. Challenge your level of skills by performing function operations, such as Addition and Subtraction of Functions, and practice Graphing Functions and their Inverses.
