[b]Introduction to graph transformations [/b] – The video begins by suggesting that all graphs in a family are related in some way. There follows a useful explanation of function notation linking the notation to the inputs and outputs of a function machine.
The four graph transformations; translate parallel to the y axis, translate parallel to the x axis, stretch from the x axis parallel to the y axis and stretch from the y axis parallel to the x axis are described in terms of how they are written using function notation. This video does not show the graph transformations but can be used as a useful introduction to the other four videos in this series.
