When I taught inverse functions last year, I really wanted students to have a context to apply them to. In the past, I just taught them the steps to write inverse functions and the concept was definitely lost on them.
So I came up with this little exploration activity to help them see how inverse functions are related to each other. It's all based on a fictional trip to Europe where students convert money and temperatures.
