Reflections of Functions
In this lesson on reflections of functions, the instructor provides an overview of how to find reflections and ties together the concepts of vertical and horizontal shifts. They explain that multiplying a function by negative one results in a reflection about the x-axis and changing the input of a function to negative results in a reflection about the y-axis. The instructor emphasizes the importance of understanding the difference between these two types of reflections and how to identify them.

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.
- What happens to the y-coordinate in -f(x)?
- What will (4,2) in f(x) be in -f(x)?
- What will (4,2) in f(x) be in f(-x)?
- In which graph would the transformation -f(x)=f(-x)?
