1.8 How to find the inverse of a linear function- Online Tutor- Free Math Videos

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 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 ca
