Inverse Function Basics
- A B Cron
Finding the inverse of a point leads to finding the inverse of relations and function. The inverse of a function occurs graphically when you interchange the x-value and y-value of a point. I.e., if point A(3 ,4) is graphed, its inverse point B(4, 3) is graphed. With functions this extends through out the domain of the function; however, the inverse of a function may itself not be a function. In order that the inverse of a function is a function, it will be necessary to limit the domain of the function that you graph. The handout will take us through several functions to determine which functions have inverses throughout their domains and which do not.
This application can be used by teachers and students as a learning tool.
