    1.3 Find the domain of the function algebraically

    http://www.freemathvideos.com n this math tutorial I describe how to find the domain of a function by determining when the bottom of a rational function is zero and when the root is negative. I also might look at the graph and determine the intervals for the domain of the function. For a rational expression we set the bottom of the rational expression to zero and solve for x. For a function with an even root we set the radicand greater than or equal to zero and solve for x. 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 exaclty 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: Blogger: www.mrbrianmclogan.blogspot.com Twitter: @mrbrianmclogan Facebook: mrbrianmclogan
