Evaluate the limit of a piecewise function by graphing

The video tutorial explains how to graph piecewise functions, specifically y = 1 and y = 0, with constraints. It demonstrates how to identify and graph these functions separately and then combine them. The tutorial also covers the concept of limits, particularly as x approaches 2, and highlights the difference between the limit of a function and its actual value at a point. The instructor emphasizes understanding the graphical representation and the importance of distinguishing between limits and function values.
