This lesson teaches you how to evaluate a piecewise function by understanding the two functions inside and the constraints of each. When evaluating a regular function, you simply plug in the value you want to evaluate for, but with a piecewise function, you must consider which function to use based on the constraints. By working through examples of evaluating the function for negative 1 and zero, this lesson demonstrates how to use the constraints and functions to arrive at the correct answer.
How to evaluate 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.
