Answer:

Domain: #x# does not equal #0#
Range: #y# does not equal #4#

Explanation:

To find the domain, ask "What can or can't #x# equal?"

In this case, #x# can equal anything but zero, since you can't divide by zero.

To find the range, we can simply say that since x can equal anything but zero, #1/x# equals everything but zero.

Therefore, the range is #y# does not equal 4.
