Where do I look for the domain in this-

The domain of y =1/(x-6) + 3

Possible answers:
All real numbers except x=6
All real numbers except x = -6
All real numbers except x=3
All real numbers except x= -3
Thank you

the function is undefined when x = 6 because of the zero denominator
so the answer is x = 6 according to what you're saying? and the domain is the (h) in here correct? So in the future I just look for the h , take the opposite and that is my domain?
