We saw that they could be called f(x) or g(x) or any letter. In this video, we’re going to look at composite functions - which makes use of different letters. Composite functions are actually used the whole time - and often without people even realising. Whenever a change in one quantity produces a change in another, which in turn produces a change in a 3rd quantity… we have a composite function. This could be human’s cutting down trees in rainforests, which therefore affects orangutan populations. It could be the number of hours you work in a week affects your weekly salary, which in turn affects your commission. A composite function is made up of several functions, performed in a certain order.
