Did you know that you can track the "behavior" of a function? Well, you can, and I'm not talking about whether the function is making curfew or not. When we talk about the "behavior" of a function, we look at how the function "shows up" when graphed. As we solve the function, we can get closer and closer and closer - the limits helps us to understand this movement of the function on the graph.
Here are some additional resources that provide a more in-depth exploration of this topic.
