Lesson Summary:

In this lesson, you will learn how to find the domain and x-intercepts of a logarithm function with horizontal shift. By taking what's inside of your function and setting it greater than 0, you can determine the domain of the logarithm. You can also find the vertical asymptote by setting the shifted function equal to 0. Finally, you can find the x-intercept by setting the function equal to 0 and solving for x. Overall, this lesson provides helpful tips and tricks for working with logarithms with horizontal shift.

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.
