In this present investigation, we introduce a certain subclass Sq (λ, γ, h) of analytic functions which is specify in terms of a quasi-subordination. Sharp bounds of the Fekete-Szegő coefficient for functions belonging to the class Sq (λ, γ, h) are obtained. The results presented give improved versions for the classes involving the quasi-subordination and majorization.
