The basic aim of this manuscript is to investigate the cosmological solutions in the context of the modified f(R, T) theory of gravity, where R is the Ricci scalar and T is the trace of the energy-momentum tensor. For our current work, we consider the Friedmann–Robertson–Walker spacetime for finding the solutions of field equations. We investigate the nature of universe by considering acceleration expansion of universe, ultra-relativistic universe, sub-relativistic universe, dust universe, radiation universe, stiff universe. Moreover, we apply the power law technique by taking two different f(R, T) gravity models to observe the expanding nature of the universe. The bouncing scenario is also discussed by choosing some particular values of the model parameters and observed the energy conditions, which are satisfied for a successful bouncing model. It is also concluded that some solutions in f(R, T) theory of gravity supports the concept of exotic matter and accelerated expansion of the universe due to a large amount of negative pressure.
