The paper deals with some relations between function spaces and their domains concerning selection principles of the form \(\mathrm{S}_1(A,B)\) and \({\mathrm{S}_{\text{fin}}(A,B)}\), for variations of covering and density properties. More precisely, the authors study the relationship between selection properties of (open, omega, gamma) covers of a topological space \(X\) and selection properties of dense subsets of \(\mathrm{USC}_p^\star(X)\) and \(C_p^\star(X)\), respectively the space of real upper semicontinuous bounded functions and the space of continuous bounded functions, both of them endowed with the topology of pointwise convergence.
