We discussed the idea that the inverse will undo an action or series of actions. We gave mathematical and real life examples of life. We completed our notes on graphing inverses, writing the formula for the inverse function and determining if the inverse is a function. We used the HLT to determine if the inverse is a function.
You may watch this short video in class that explained the idea of a function being one-to-one.

We also found that the graphs of the original function and its inverse are reflections over the line y = x. Their ordered pairs are also switched.
