Have you ever been in the middle of telling a story and had to use hand gestures or even a drawing to make your point? In algebra, if we want to illustrate or visualize a key feature of a function, we sometimes have to write the function in a different form—such as a table, graph, or equation—to determine the specific key feature we’re looking for. Think about your interactions with others and situations you’ve come across in your own life. How have you had to adjust or change the way you represented something based on either the concept you were trying to describe or the person you were interacting with?
