    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|
