The problem asks to determine the domain of the given graph.

The domain of a function refers to the set of all possible $x$-values for which the function is defined. From the graph in your image, the function starts at approximately $x = -10$ and ends at $x = 10$ (there is a closed circle at $x = 10$, indicating that this point is included in the domain). Therefore, the domain includes all $x$-values from $-10$ to $10$, inclusive.

Thus, the domain of the function is: $\boxed{[-10, 10]}$

Would you like further details or have any questions?

Here are 5 related questions you might consider:

1. How do you determine if an endpoint is included in the domain?
2. What is the difference between the domain and range of a function?
3. Can a function have a domain that extends infinitely in both directions?
4. How do vertical asymptotes affect the domain of a function?
5. What is the domain of a function defined by a rational expression?

Tip: The domain is affected by factors like breaks in the graph (e.g., holes, jumps), asymptotes, and points where the function is not defined. Always check carefully for such features!
