Function Composition – Deeper Understanding

_________________________________________________________________________________
A simple twist on the typical exam question.  Do pupils appreciate that each point on a graph is an instance of (x, f(x)) ?  Do they realise that the composite function has coordinates (g(x), f(g(x)) ?

This graph could be presented to pupils.  Then have them select pairs of points to put in the table to notice the relationships and explore the underpinning principles of composition.
