Best ResponseYou've already chosen the best response.2@confluxepic it can't be all values of x because x is in the denominator.

Best ResponseYou've already chosen the best response.2Try to figure out ALL of the values of x that are not in the domain.

Best ResponseYou've already chosen the best response.0you should be more certain. the way you know the answer is remember NO divide by zero some values for x will cause the bottom to be zero, and we do not allow those

Best ResponseYou've already chosen the best response.2@vera_ewing I agree with @phi. If someone challenges any answer you choose, you should be ready to defend your answer.

Best ResponseYou've already chosen the best response.0notice if x=0 you would get 0* (081) = 0*81 = 0 and the bottom would be 0, and that is bad. so you should look for choices that say \( x\ne 0\)

Best ResponseYou've already chosen the best response.0Yes @hero I was just stating the definition of the domain to help the asker understand. I guess it would have been clearer if I added "possible" to the definition to make it more accurate.
