The domain is all the values of x.
Hero
  • Hero
@confluxepic it can't be all values of x because x is in the denominator.
Hero

@vera_ewing it's not B
vera_ewing
  • vera_ewing
Would it be A?
Hero
  • Hero
Try to figure out ALL of the values of x that are not in the domain.
vera_ewing
  • vera_ewing
So then it's D? That was my first choice.
Hero
  • Hero
Sorry I didn't see your first choice. I only saw B.

D is correct.

you 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

Thank you.

All right, @phi Thanks.

@vera_ewing I agree with @phi. If someone challenges any answer you choose, you should be ready to defend your answer.
phi
  • phi
notice if x=0 you would get 0* (0-81) = 0*-81 = 0 and the bottom would be 0, and that is bad. so you should look for choices that say \( x\ne 0\)

Thanks so much, @phi and @Hero

Yes @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.
