Moreover, we give the some refinement of these obtained Hermite-Hadamard-Fejer inequalities utilizing two mapping. The inequalities obtained in this study provide generalizations of some result given in earlier works.en10.31801/cfsuasmas.748013info:eu-repo/semantics/openAccess[No Keywords]Article701100116WOS:000663383900002N/A
