Transformations of Graphs

Hi Everyone!

     I hope December is treating you well so far. In our SL Math course at the moment, we have reached Chapter 5: Transformations of Graphs. So far we have breezed through this chapter. but this does not mean that is was particularly easy. The hardest part about this chapter was identifying all of the different rules in relation to transforming graphs and applying them correctly to each question. The book that we study from has its fair share of good teaching styles and bad ones. Therefore, the 3 of us tend to refer to our teacher, Ms. Crystal, as well as the back of each chapter for some key points that we have to remember. Here is a little snippet of the back of Chapter 5:

   One last rule that we have been told to remember is to follow H.S.R.V. H stands for Horizontal, S stands for Stretch/Shrink, R stands for Reflection, and V stands for Vertical. This is the order in which you should always transform your graph, otherwise it will come out wrong. If you need help making sense of the rules in the picture above, or the H.S.R.V rule, do not hesitate to ask in the comments!
