To find $f(2)$ from the graph, we need to observe the value of the function at $x = 2$.

From the graph:

• At $x = 2$, the point is indicated by an open circle, meaning the function is not defined at $x = 2$.
• Therefore, $f(2)$ is undefined or does not exist at that point.

Would you like more details on how open and closed circles affect function values? Here are some follow-up questions to expand your understanding:

1. What is the significance of a closed circle on a graph?
2. Can a function be defined at a point with an open circle in any other scenario?
3. What does the graph tell us about $f(3)$?
4. How do we find the limit of $f(x)$ as $x$ approaches 2?
5. What is the difference between the domain and range of a function?

Tip: Open circles on a graph signify points where the function is not defined at that specific value, while closed circles show where the function takes a specific value.
