We introduce some families of functions f : R → R modifying the Darboux property analogously as it was done by [Maliszewski, A.: On the limits of strongŚwiatkowski functions, Zeszyty Nauk. Politech. Lódź. Mat. 27 (1995), 87-93], replacing continuity with A-continuity, i.e., the continuity with respect to some family A of subsets in the domain. We prove that if A has (*)-property then the family D A of functions having A-Darboux property is contained and dense in the family DQ of Darboux quasi-continuous functions. Ò Ø ÓÒ 2 ([14])º A function f : R → R has the strongŚwiatkowski property if for each interval (a, b) ⊂ R and for each λ ∈< f (a) , f (b) > there exists a point x 0 ∈ (a, b) such that f (x 0 ) = λ and f is continuous at x 0 .
