How to decompose a function into a composition

The video tutorial explains the concept of composite functions, where one function is inside another. It identifies the inner function G(x) and the outer function F(x), using examples involving absolute value and linear functions. The tutorial also discusses multiple solutions and common mistakes in function composition, providing alternative solutions and variations.

Describe the relationship between absolute value and the functions mentioned.

What are some possible answers for G of X based on the discussion?
