Vacuum solution of lrs bianchi type-i model in f(r) theory of gravity

In this paper we have obtained vacuum solution of locally rotationally symmetric (LRS) Bianchi type-I model in theory of gravity assuming that the expansion θ is proportional to the shear scalar σ and hybrid scale factor is used to find the deterministic solution of the model. Also physical behavior of the model are also discussed and the function of the Ricci scalar is evaluated.
