Here's a quick activity to develop the idea of inverse functions for my algebra 2 students. We just learned composition and domain and range. I hope it'll be fun.

Update: We just did this activity. The game was GREAT. The worksheet was terrible. I need to tweak it. I'll upload a new version once I think it'll work better.
Update update: Here's a new version of the worksheet. I'm actually kinda proud of this one. I want to go back in time and kick myself. Or at least hand this over to past me and make me teach it this way instead.
