Graphically modelling an equation that utilizes the answer feature

Is there a method to model an equation that would utilize the previous Y value in the equation when graphing it? For reference what I am trying to graph is an equation that utilizes a current % of the Y value when computing the new Y value. Mathematically I understand that this can be done utilizing the answer function, but I don’t know if there is a way to graphically demonstrate it.

Hi Alex! My initial impression is that sounds doable - can you share a specific example of what you’re thinking? Details like, what exact number or equation might a student type in, what calculations happen, etc. An example with concrete numbers could help us give you more relevant answers :slight_smile:
