Piecewise and Linear Functions Concepts

The video tutorial covers graphing piecewise functions, starting with an easy example and progressing to a more complex one. The easy example involves linear equations with domain restrictions, while the hard example includes absolute value and quadratic functions. The tutorial emphasizes understanding domain restrictions and the vertical line test, providing a comprehensive guide to graphing these functions step-by-step.
