The case of approximation by linear combinations is also considered. Applications are given for some Szasz-Mirakyan and Baskakov-type operators.eninfo:eu-repo/semantics/closedAccessLinear combinationslinear positive operatorsVoronovskaja's theoremSzasz operatorsBaskakov operatorsPhillips operatorsArticle27345946810.1515/gmj-2018-00412-s2.0-85049233712Q2WOS:000565809500015Q4
