Graphing absolute value equations with a reflection and horizontal stretch and translations

This video tutorial explains how to graph an absolute value inequality. It begins by identifying the new vertex after transformations and discusses the effect of the coefficient on the graph's horizontal stretch. The tutorial uses a table of values to find points on the graph, calculates Y values for chosen X values, and completes the graph by reflecting points over the axis of symmetry.

What is the significance of the axis of symmetry in the absolute value graph?

How do you determine the y-values for chosen x-values in the absolute value equation?
