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.
