Sketching Composite Functions
- For details on how to find composite functions, please refer to 4.1 Composite Functions in A2 – Algebra. This section mainly concerns some guidance on how to sketch them.
- Suppose we know f(x) and g(x), and we want to sketch h(x)=f(g(x)). Of course we can construct a table below (suppose g(x)=x^2+7,\ h(x)=x-1):
