Graphing an absolute value function with a vertical shift

The video tutorial explains how to graph absolute value functions using different methods, including the table method and transformations. It covers the effects of negative signs and coefficients on the graph, and demonstrates how to use points to plot the graph. The tutorial emphasizes understanding transformations, such as shifts and reflections, and how they affect the graph's appearance.

What is the effect of shifting the graph up or down?

Describe how to determine the vertex of the graph of an absolute value function.

How can you verify the graph of an absolute value function using specific points?
