This lesson teaches how to evaluate a quadratic function by inputting a variable into the equation and simplifying it. The quadratic function given is f(x) = 3x² - 2x + 2. By inputting -1 and 1/3 into the function, students learn how to find the output value. The lesson emphasizes the importance of having unique output values for a function and simplifying the equations to get the correct answer.

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.
