Algebra II: Lesson 2.1 - Introduction to Absolute Value Functions

In this lesson, we discuss the definition of absolute value as an operation and its definition as a piecewise function, how to graph an absolute value function using its piecewise definition and how to graph using function transformations, and the importance of utilizing the multiplicative property of absolute value. There is also an unrelated piece at the end of the video reviewing how to isolate an expression (no matter how complicated it looks).
