Okay. What has he done? Where is he stuck? (In order to help him, we need to know what he has tried and what his thoughts are. If he could reply directly, or at least dictate the reply, that would be great.)

For Domain we got ARN

What is an "ARN"?

I am not sure about the range--

What does your son think? What definition has he learned? What method(s) does he have with which to work? For instance, has he looked at the graph? If so, what did he conclude?

Please be complete. Thank you.
