Graphing an absolute value equation with a vertical shift

The video tutorial explains how to graph the function X = 2|X| - 8. It begins by introducing the concept of the parent function for absolute value graphs, which is the absolute value of X. The tutorial then discusses how multiplying the absolute value function by 2 results in a vertical stretch and horizontal compression. Finally, the video covers the transformation of the graph by shifting it 8 units down, resulting in the final graph. The tutorial emphasizes understanding the effects of multipliers and shifts on the graph's shape and position.
