Answer:
The answer is A
Step-by-step explanation:
The Domain is all the possible "X" value of the graph, so all the points' "X" values that are being touched by the line. So we know that the "X" values stop at certian points, which are the "X" values -6 and 6, so all the "X" values between them and including them are being touched by the line.
