The video tutorial explains how to apply transformations to functions, using an arbitrary function f(x) as an example. It covers the concept of parent graphs and how transformations such as vertical and horizontal shifts, reflections, and stretching affect these graphs. The tutorial provides detailed explanations and examples to illustrate these transformations, ensuring that viewers understand how to apply them to any function.

Which of the following is an example of a function that could be represented by f(x)?

• All of the above

• x^3

• log(x)

• sin(x)
