Summary: We introduce a positive linear operator in the space of continuous functions, having exponential growth at infinity. We investigate the order of approximation of a function \(f\) by means of the considered operators. The method was inspired by A. Jakimovski and D. Leviatan [Mathematica, Cluj 11(34), 97-103 (1969; Zbl 0188.36801)].For the entire collection see [Zbl 1007.00036].
