About this lesson
This video is the second in the series for Year 11 Mathematical Methods looking at Transformations of functions. Building on the previous video I now look at how we might look at reflecting and dilating functions. I look at a number of examples and approaches including substitution algebra and direct substitution. I explain every example in an easy to understand way but deep enough to help you smash any test or exam.
