    Is this all the information the problem gives you?

    If it's asking for domain, all real numbers except for zero. For range, also all real numbers except for zero.

    So now that you've told her the answer it could be a good idea to explain why, then next time she can figure it out alone and take less time than this takes.

    Alright ... (1/x) can take nonzero number. To make this very negative, simply put in a very close-to-zero but negative x. To make it very positive, simply put in a very close-to-zero but positive x. To make it near zero, simply put in a very positive or very negative x. But no matter what x you put in, you will never get zero. There are asymptotes at both x = 0 and y = 0.|dw:1354227575994:dw|
