# Composite Functions

In this mathematics lesson students learn how to find the output of composite functions using the correct notation.  As learning progresses they are challenged to generalise outputs in terms of x.
##### Differentiated Learning Objectives
• All students should be able to use a function machine to break down the composite functions in the form gf(x).
• Most students should be able to generate outputs from composite functions and realise that fg(x) does not give the same output as gf(x).
• Some students should be able to use algebra to determine the input of a composite function when given the output.

Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]

#### How to Solve Quadratics by Factorising

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have.   Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]
