In this work, we study different aspects of the growth of matter density perturbations for some viable f(R) models that satisfy both cosmological and local gravity constraints, where the Lagrangian density f is a function of the Ricci scalar R. More specifically, we''ll look at some properties that may be useful in the quest for f(R) modified gravity models using future high-precision observations and that confirm the possibility to distinguish these models from the Lambda-CDM model for a certain range of parameters.
