Some measurability and continuity properties of arbitrary real functions

Given an arbitrary real function <em>f</em> , the set <em>D_f</em> of all points where <em>f</em> admits approximate limit is the maximal (with respect to the relation of inclusion except for a nullset) measurable subset of the real line having the properties that...
