Lesson Summary:

This lesson teaches you how to evaluate a piecewise function, which is a function that contains two other functions with constraints. The constraints determine which function to use for a specific input value. By understanding the constraints, you can determine where to plug in the input value and get the correct output. The lesson provides an example of evaluating f of negative 3 and f of 10 with the given constraints.

Lesson Description:

Evaluating a piecewise function

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.
