Answer:
The first answer choice.
Answer choice A.
Explanation:
The domain of a function would be the set of all possible x-values of that function.
Since we are looking for the domain, the set of the possible x-values, we can eliminate any answer choices that are a set of y-values. B and D are eliminated.
From what we can see in the table, the possible x-values of the function are -6, -1, 0 and 3. Although C does include these values in the set, it also includes many other values. As we can see, answer choice A includes the x-values given in the table and only those values. Therefore, answer choice A is the correct answer.
