About This Lesson
http://www.freemathvideos.com In this video I show I show you how to evaluate a function and expression for a given value. We do this by plugging in" the value into the input variable of the function and then simplifying. 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. Please visit http://mathhomeworkanswers.org and type in your homework questions
