In this paper, we study a LRS Bianchi type-I cosmological model in the framework of symmetric teleparallel f (Q) gravity in which the non-metricity term (Q) is responsible for the gravitational interaction. We have considered a special form of the f (Q) gravity function which can be cast as f (Q) = γ Q n (where γ and n are both the dynamical model constant parameters). Such a choice can be viewed as a hybrid scale factor and the cosmic time and the redshift are related viawhich describes a ΛCDM model of the Universe with the expansion evolving from decelerating to an acceleration phase. We further study the validity of our model with an investigation of the thermodynamical quantities and energy conditions along with some physical variables such as the EoS, jerk, and statefinder parameters. Our results are discussed in the light of current observational data and trends.
