We study the system of functions λ1+n(x) generated by the system of Laguerre functions. We express functions λ1+n(x) in terms of Laguerre polynomials \(L_n^\alpha (x)\). Using the obtained representations and asymptotic formulas for polynomials \(L_n^\alpha (x)\), we study the behavior of functions λ1+n(x) on [0,∞) with n →∞ and deduce estimates analogous to those for Laguerre functions.
