Name a function with a domain of all real numbers that is continuous only at a single point.
Definition: A function is continuous at point B if and only if the limit of f(x) as x approaches B is equal to f(B).
These examples are pretty cool, but all use the same idea of a piecewise function based on the discontinuity of the rational numbers within the reals.
Is there another way to do it either nonpiecewise or not using the rationals?
