The concept of measurability of real-valued functions with respect to various classes of measures is introduced and the associated notion
of an absolutely nonmeasurable function is investigated. A characterization of such functions is given. Also, it is shown that functions produced by the classical Vitali partition of the real line are measurable with respect to the class of all extensions of the Lebesgue measure on this line.
Absolutely nonmeasurable function, generalized Luzin set, Vitali partition, extension of measure.
