Recently in Pre-Calc we have been learning about inverse functions! This activity helped me understand them a lot better. Our math teacher came up with this cool idea to teach us in a different way by using a piece of plastic paper, dry erase marker and a ruler. We as a class used the function "y=x^2." To find the inverse of this function you have to change all of your x's to y's. Then, take the square root of the entire function. We originally graphed the function "y=x^2," then graphed the second function. We then graphed y=x on our plastic sheet making a dotted line. After all that, we then folded our plastic sheet on the dotted line and our two graphs lined up. My whole class was amazed by this. In the end, the inverse function was not a function. It did not pass the verticle line test. Although functions can also have an inverse that is a function. It is possible. For example, y=x. overall, I really like this project and it made me understand inverse functions better and how they work!
