Best ResponseYou've already chosen the best response.1Umm u dont even actually have to set up.. just apply this few rules (1) anything divided by 0 ( a fraction) is undefined so for (a) square root of (1/x + 1) u know that 1 over 0 is undefined when x = 0 so ur domain would be x cannot be equal to 0.. as simple as that

Best ResponseYou've already chosen the best response.0Do I need to think about the negatives as well?

Best ResponseYou've already chosen the best response.1yes.. for example 1/(x+1).. ur x cannot be negative one cause 1 +1 = 0

Best ResponseYou've already chosen the best response.0For a) if the denominator was negative, it would make the equation inside the sqrt negative

Best ResponseYou've already chosen the best response.1even if x is 100000000000 its 1 OVER it.. thats like 0.00000000000 bla bla bla
