How to Graph a Piecewise Function With Three Equations

The video tutorial covers graphing inequalities with three different equations, focusing on domain and range restrictions. It begins with an introduction to the topic, followed by step-by-step graphing of each equation, including handling open and closed intervals. The tutorial concludes with an analysis of the domain and range, highlighting jump discontinuities and voids in the range.

Explain the concept of jump discontinuities as described in the text.

What is the range of the graph as discussed in the lesson?
