GUIDE TO ABSOLUTE VALUE TRANFORMATIONS!

ßy = |x + h| the graph will move h unites to the left. ày = |x – h| the graph will move h units to the right.

̂y = |x| + k the graph will move up k units. ˇy  = |x| – k the graph will down k units.

o   If you have a negative sign in front of the absolute value, the graph will be flipped over the x-axis.
