1.8 - Finding the inverse of a rational function with a root as a denominator - coolmath


By Mr. McLogan's Math Channel

In this video tutorial I will show you how to find the inverse of a function f(x). I do this by first writing the equation substituting y for f(x). I then solve the equation for x. The result is the inverse. The inverse can be written, substituting y back in for x, and x for y. I also show how to verify that a function is an inverse of another function. I am a math teacher that provides free online math tutoring by working through problems for the website www.freemathvideos.com 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.
