We provide sufficient conditions for a sequence of positive linear approximation operators, L n ( f, x), converging to f (x) from above to imply the convexity of f. We show that, for the convolution operators of Feller type, K n ( f, x), generated by a sequence of iid random variables taking values

## In the present paper, we study the rate of pointwise approximation by a new sequence of linear positive operators for functions of bounded variation. To prove the main result, we have used some results of probability theory. In the end, we also introduce the Bezier variant of these newly intro
