Özet
In this study, we introduce a q-analogue of the Phillips operators and investigate approximation properties. We establish direct and local approximation theorems. We give a weighted approximation theorem. We estimate the rate of convergence of these operators for functions of polynomial growth on the interval [0, infinity).
