25 A level Mathematics Composite Functions Part 1

In this A-level Mathematics video, Christina introduces the concept of composite functions, starting with part one of the series. You will learn the formal definition of a composite function and understand the notation used to represent them, specifically fg of x. The video explains how the output of one function becomes the input for another, breaking down the process with clear examples. Discover how to combine functions like f(x) = 3x and g(x) = 5 + x to find the composite function fg of x. Subscribe to @AxiomTutoringCourses for more A-level Maths tutorials.
