The question asks about the domain of the function represented in the graph. The domain refers to the set of all possible $x$-values for which the function is defined.

Analysis of the Graph:

• The graph starts at $x = 2$ (indicated by the point at $(2, 6)$).
• The graph ends at $x = 8$ (indicated by the point at $(8, 0)$).

Thus, the function is defined between $x = 2$ and $x = 8$, inclusive. This means the domain of the function is $2 \leq x \leq 8$.

Correct Answer:

• The correct choice is B: $2 \leq x \leq 8$.

Let me know if you want more details or have any further questions.

Here are some follow-up questions related to this concept:

1. What is the range of the function shown in the graph?
2. How do you identify the range of a function from its graph?
3. What is the slope of the function on the graph?
4. How would the domain change if the graph extended beyond $x = 8$?
5. What is the difference between the domain and range of a function?

Tip: When analyzing a graph for domain, focus on the $x$-values along the horizontal axis that the function covers.
