In this mathematics lesson students learn how to find the inverse of a function using function machines. As learning progresses students use transposition of formulae and recognise inverse functions as a reflection of its original in y = x.
Differentiated Learning Objectives
- All students should be able to use function machines to find an inverse function.
- Most students should be able to find an inverse function using algebraic methods.
- Some students should be able to draw the graph of an inverse function using a reflection on y = x.
