Determine whether an equation determines y as a functions of x

http://www.freemathvideos.com In this video series I show how we determine the difference between a relation and a function. A function is a relation where every input value maps to exactly one output value. Every function can be written in function notation. I am a math teacher that provides free online math tutoring by working through problems for the website http://mathhomeworkanswers.org. These questions are usually to help students understand their math homework or to do well on their math test. The videos are made for students that want help with math and want to be shown a step by step process into solving the problems. In addition to solving the problems I also offer explanations into why I am doing each step. I offer free math videos so that my students can learn math online if they missed a day of school. However I also like to answer questions that are not apart of what I currently teach. x + y = 9 x^2 + y^2 = 1 x = y^2
