To determine the domain of the graph, we need to identify all possible values of $x$ for which the graph is defined.

From the provided graph:

• The graph extends horizontally from $x = -12$ to $x = 12$.
• There is no break in the graph between these points, which means the graph is continuous within this range.

Thus, the domain of the graph is:

$\boxed{[-12, 12]}$

This means that $x$ can take any value between $-12$ and $12$, inclusive.

Would you like further details or have any other questions? Here are some related questions you might consider:

1. What is the range of this graph?
2. How do you determine the domain of a function from its equation rather than its graph?
3. What is the difference between open and closed intervals when describing a domain?
4. How do you find the domain of a piecewise function?
5. How does the domain change if the graph is shifted horizontally?

Tip: When determining the domain from a graph, look at the extent of the graph along the x-axis to see where the graph starts and ends.
