This is the third video in the series looking at how to transform functions. Building on the work from doing basic and single transformations (dilations, reflections and translations) this video looks at how we might combine transformations; that is, use more than one. I look at the idea of Dr T (or DRT) and how this might be applied when the order isn't given in the question. I show examples of how to use direct substitution and how to use substitution algebra. The examples are kindly used with permission of Cambridge VCE textbooks.
