The graphs below show what happens when you graph y equals vertical line x plus 2 vertical line  and y equals vertical line x minus 2 vertical line .

  Graph y = the absolute value of x + 2 and y = the absolute value of x minus 2.
Image Long Description

For a positive number h, y equals vertical line x plus h vertical line  translates the graph of y equals vertical line x vertical line  left h units, and y equals vertical line x minus h vertical line  translates the graph of y equals vertical line x vertical line  right h units.
