Lesson Summary:

In this lesson, you will learn how to combine different functions using four basic operations: adding, subtracting, multiplying, and dividing. The instructor uses examples to show how each operation is applied to two functions, such as F(x) = x² and g(x) = x + 2, and how to simplify the resulting combined function. The lesson also touches on finding the domain of the combined function when dividing. The instructor hints at exploring function composition in future lessons.

Overview of combining functions

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.
