Best ResponseYou've already chosen the best response.0when i plug in 3, i get 10/0...thats not good according to my teacheelser but dont know what else to do

Best ResponseYou've already chosen the best response.0right, /0 is a bad fraction so x=3 makes this go bad

Best ResponseYou've already chosen the best response.0can we undo the offending part with algebra?\[\frac{(x+7)}{(x3)^2}\] prolly not

Best ResponseYou've already chosen the best response.3lol i love your definition of the term bad fraction i like to say discontinuous at such and such but bad fraction is a good term

Best ResponseYou've already chosen the best response.3So anyways since there is no way to force this fraction to be continuous at x=3 then the limit does not exist

Best ResponseYou've already chosen the best response.3does not exist is fine but saying it approaches infinity gives a little more info on that "does not exist" phrase

Best ResponseYou've already chosen the best response.0exist means a definitive value; infinity is more a direction than a value i believe

Best ResponseYou've already chosen the best response.3infinity is fine to say when both sides are approaching infinity (same for negative infinity) but i feel it is also okay to say it dne since infinity is not a number

Best ResponseYou've already chosen the best response.0For this question I would say that the limit is infinity, but if for the purposes of some questions where only finite limits are applicable then an infinite limit might be considered DNE.

Best ResponseYou've already chosen the best response.1I'd probably say infinity too, but with the understanding that the limit really does not exist...infinity is just the direction that the function is going.
