The question asks to list the domain for the set of points $B = \{(-2, 5), (3, 4), (6, 2), (3, -4)\}$.

The domain of a set of points refers to the set of all the x-values (the first elements in each pair).

From the set $B$, the x-values are:

$\{-2, 3, 6\}$

Note that $3$ repeats twice, but in the domain, each value is listed only once.

Thus, the domain is:

$\{-2, 3, 6\}$

The correct answer is B.

Would you like further details or have any other questions?

Here are some related questions to consider:

1. What is the range of this set of points?
2. How do you determine the range in a relation?
3. Can a domain contain repeated values?
4. What happens if two different x-values share the same y-value?
5. What are the key differences between a function and a relation?

Tip: The domain refers to all possible input values (x-values), while the range refers to all possible output values (y-values).
