The question in the image is asking about whether a given graph represents a function, and then about the domain of that function.

- **Is this the graph of a function?** You selected "Yes." This suggests that the graph passed the vertical line test, meaning it represents a function (each x-value corresponds to exactly one y-value).

- **What is the domain?** 
   - Option A asks for the domain in the form of an inequality or a compound inequality.
   - Option B states "The domain is all real numbers," meaning there are no restrictions on the x-values.
   - Option C claims "The graph does not represent a function," which does not apply since you selected "Yes" earlier.

To select the correct domain, you would need to examine the range of x-values the graph covers. If the graph stretches across the entire x-axis with no breaks or restrictions, the domain would likely be all real numbers (Option B). If the x-values are restricted (e.g., the graph only exists between two specific x-values), you'd need to input those values as an inequality (Option A).

Would you like further assistance with analyzing the specific graph? 

Here are five questions to expand your understanding:
1. How can you use the vertical line test to determine if a graph represents a function?
2. What are some common domain restrictions for functions (e.g., square roots, rational functions)?
3. How do you represent domain restrictions using inequalities?
4. If a graph has endpoints or breaks, how does that affect the domain?
5. Can a function have a domain that is not all real numbers, but still be continuous?

**Tip:** Always check for any breaks or holes in a graph to ensure there are no restrictions on the domain.

Is this the graph of a function? What is the domain?

Learn how to determine if a graph represents a function using the vertical line test and identify its domain. This lesson focuses on understanding functions, the domain and range, and how to apply inequalities to define restricted domains. Suitable for students in Grades 8-12.
