How to determine and label if a piecewise function is continuous or not

The video tutorial explains how to graph piecewise functions, focusing on the absolute value of X + 1 and the horizontal line Y = -1. It covers graph transformations, constraints, and domain exceptions, emphasizing the importance of understanding graph continuity and identifying holes. The tutorial guides students through using graphing calculators and manual graphing techniques to visualize these functions.

How does the graph change when X equals 3, according to the text?

Explain why the graph is not continuous based on the information provided.
