In this paper we have derived the behavior of deceleration parameter withrespect to redshift in context of f(R) gravity in vacuum using Taylor expansionof derivative of action. Here we have obtained that the two first terms inTaylor expansion may describe the late time acceleration which is appeared bySNeIa without need of dark energy and dark matter. Also we have derived thatany other terms higher than z in Taylor expansion may describe maininflationary epoch in the early Universe. We have shown that f(R) gravity maycover all the dynamical history of the Universe from the beginning to the latetime accelerating phase transition.
