Characteristics of a Quadratic Equation
In this lesson, you'll learn how to determine the y-intercept, axis of symmetry, vertex, whether it's a max or a min, and the domain and range for a quadratic equation. The instructor breaks down the formula for each of these characteristics and uses an example to demonstrate how to find them step by step. They also explain how to determine if the vertex is a maximum or minimum point and how to find the domain and range of the function.
How to determine the y intercept, vertex, axis of symmetry, domain, range of a quadratic equation
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.

Staff Review
The instructor uses one example of a quadratic function and shows how to find the following y-intercept, axis of symmetry, vertex, domain, and range. His example is fairly clear and easy to follow.
