The domain of a function is the set of all possible $x$-values that the function can take. Based on the points provided $(-2, 6)$, $(0, 6)$, and $(1, 0)$, the $x$-values are $-2$, $0$, and $1$.

So, the domain is:

$\text{Domain} = \{-2, 0, 1\}$

Would you like more details or have any questions?

Here are some related questions you might find interesting:

1. What would the range be if another point, say $(2, 8)$, was added?
2. How do you determine the domain of a function when given an equation instead of points?
3. If the graph were extended, how might the domain and range change?
4. What is the significance of having repeated $y$-values (like the two 6s in this example)?
5. Can a domain or range ever be an empty set?

Tip: When dealing with graphs, always carefully check each point to accurately determine the domain and range!
