Introduction to Composite Functions in Mathematics

The video tutorial explains how to combine functions by forming a chain, where the output of one function becomes the input of another. It provides examples using simple functions and demonstrates the process of substitution. The tutorial also explores a more complex example involving three functions and discusses how to determine the range of the resulting function.

What is the result of the composition gf of x based on the functions discussed?

Describe how to determine the range of the function fhg of x.
