In this lesson on evaluating quadratic functions, students learn how to find the value of a function at a given input. The instructor explains the different parts of a function and how to evaluate it using a specific value. They also demonstrate how to use a binomial expression to evaluate a function at a different input. Through simple examples and step-by-step explanations, students can gain a better understanding of how to evaluate quadratic functions.
Evaluate a quadratic function for two given values
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.
