It only means that in its current form as a limit put into a function, it presents too many unknowable characteristics to form an appropriate answer properly. As an example of this ambiguity, lets look at the graph of fx x 2. A formal definition of a limit if fx becomes arbitrarily close to a single number l as x approaches c from either side, then we say that the limit of fx, as x approaches c, is l.
