In this lesson, we learn about the composition of two functions, which involves plugging one function into another function. We delve into evaluating f of g of x and g of f of x, and simplifying the functions. While the square root and square of a number cancel each other out, we can't separate terms when adding or subtracting functions. Overall, composition of functions allows us to manipulate and simplify expressions in a variety of ways.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
