  Well, that's just plain wrong. In the n/x function there's a discontinuity
at x=0, which makes n/0 undefined (if you approach x->0 from the right,
the limit will be +infinity, while if you approach from the left, it
will be -infinity; it can't be both at x=0; it's a discontinuity and thus
not defined).

  If 1+infinity = infinity, then 1/(1+infinity) = 1/infinity = 0
