Graphs can sometimes make it harder to understand limits and continuity instead of making them clearer. Here are some problems people face:

• Confusing interpretations: A graph might look like it is continuous, but there can be small breaks that are easy to miss.

• Problems with scale: If the scale of a graph is not chosen carefully, it can change how we see limits and lead us to the wrong conclusions.

• Complicated functions: Some functions are tricky to look at because they behave in complicated ways, making it tough to find limit points.

To tackle these problems:

• Use interactive software that lets you zoom in on specific parts of the graph to better understand how the limits behave.

• Pair graphs with math methods, like calculating limits at certain points (like finding $\lim_{x \to a} f(x)$).

• Talk with friends about the graph data to help each other understand it better.

By handling these problems step by step, students can improve their understanding of limits and continuity.
