# Inverting Functions - Reflection visualisation

Demonstrates the reflection about the y=x line for finding the inverse of a function f(x).
Use the slider

*r*to reflect f(x) to its inverse relation, or toggle animation to let it swing back and forth. There are three different view modes - straight, swing, and bigswing, which change the perspective angle on the reflection. Different view modes may be more or less helpful in seeing the reflection for different functions. The user can change the number of points being tracked (*n*), and can shift the upper and lower bounds on where the tracking points are generated (*a*and*b*).## New Resources
