What are Composite Functions?
In this post, we define and use the composite function f(g(x)) of functions f(x) and g(x) where appropriate and identify the domain and range of a composite function. This is part of the Prelim Maths Advanced course under the topic Working with Functions and sub-part Introduction to Functions, specifically focusing on composite functions. A composite function is a function inside a function, or a function made up of another function, where the output of one is the input of another.
