Lesson Summary:

This lesson focuses on how to find the x-intercept of a logarithm with a horizontal shift. The key to finding the x-intercept is to know how to determine the domain range, and how to solve for x using exponential form. By understanding how to shift the function left or right, and how to interpret the vertical asymptote, students will be able to confidently graph and solve for the x-intercept of logarithmic functions with ease.

Lesson Description:

Find the x intercept of a logarithm with a 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.
