Lesson Summary:

In this lesson on horizontal shifts, we learn that when dealing with horizontal transformations, we use the equation t of x equals u f of x plus or minus c, and that when c is positive, we shift c units to the left, and when c is negative, we shift c units to the right. The lesson walks us through a couple of examples and shows us how to calculate the shift by evaluating the function at a specific point. It's important to remember that positive values shift to the left, while negative values shift to the right when it comes to horizontal transformations.

Lesson Description:

Overview of transformations - horizontal shifts

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.
