The Grüss-Voronovskaya-type approximation results for the modified
Gupta-Srivastava operators are considered. Moreover, the magnitude of differences
of two linear positive operators defined on an unbounded interval has been estimated.
Quantitative type results are established as we initially obtain the moments of
generalized discrete operators and then estimate the difference of these operators
with the Gupta-Srivastava operators.
