摘要：

In this research article, we construct a q$$ q $$-analogue of the operators defined by Betus and Usta (2020) and study approximation properties of these operators in a polynomial weighted space. Further, we modify these operators to study the approximation properties for differentiable functions in the same space and show that the modified operators give a better rate of convergence.
