Today we started a new unit called Transformations or Transformational Geometry. We did notes on all of the reference functions, and found the graphs we needed to know off either graphmatica or your calculator. We learned that if one of the reference functions were to slide it would only be left, right, up, or down. The equation of a sliding function is y=f(x-h)+k, where the h value represents left or right movement and the k value represents up and down movement. Be sure that when there is a question in this form that the sign infront of the h value represents opposite slide movement. ie)f(x-5)+3, the h value is -5 so you move right five units.
Check out transformations on ronblond.com, it seemed to be useful seeing the tranformations on the graphs and which movements slide which direction.
