Lesson Summary:

In this lesson, you will learn how to determine the domain, vertical asymptote, and x-intercept of a logarithm. It is important to know the general form of the graph, which will always cross at 1,0, and the domain will be 0 to infinity. The vertical asymptote is x equals 0. The base of the logarithm does not affect these aspects of the graph. To find the x-intercept, you need to set f(x) or y equal to 0 and solve for x using logarithmic arithmetic conversion to exponential form.

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.
