Abstract ：We investigate f (R ) gravity using the Noether symmetry approach. For this purpose, we consider Friedmann Robertson–Walker (FRW) universe and spherically symmetric spacetimes. The Noether symmetry generators are evaluated for some specific choice of f (R ) models in the presence of the gauge term. Further, we calculate the corresponding conserved quantities in each case. Moreover, the importance and stability criteria of these models are discussed.
