To find $f(3)$ graphically, you need to locate the point on the graph where $x = 3$ and then determine the corresponding $y$-value.

1. From the graph, observe the point where $x = 3$.
2. At $x = 3$, the function $f(x)$ has a filled dot at $y = -3$.

Thus, $f(3) = -3$.

Would you like any additional details or clarifications? Here are some related questions:

1. What does it mean when a point is marked with an open circle versus a closed circle on a graph?
2. How can you use a graph to estimate function values for non-integer $x$-values?
3. How do you determine the domain and range of the function based on the graph?
4. What is the maximum value of the function, and at what $x$-value does it occur?
5. How can we check if this function is increasing or decreasing at certain intervals?

Tip: When interpreting graphs, filled dots indicate that the point is included in the function, while open dots indicate the point is excluded.
