  Dynamical aspects of cosmological model in an extended gravity theory have
been investigated in the present work. We have adopted a simplified approach to
obtain cosmic features, which in fact requires more involved calculations. A
cosmological model is constructed using a hybrid scale factor that simulates a
cosmic transit behaviour. The deceleration parameter and energy conditions have
been obtained for the constructed model. Scalar fields have been reconstructed
from the present model in the extended gravity. Different diagnostic methods
have been applied to analyse the viability of the constructed model. The
present model almost looks like a cosmological constant for a substantial
cosmic time zone and does not show any slowing down feature in near future.
