As for the front derailleur, its role is to move the chain to change the gear (distance traveled by doing a pedal tour) according to the level of the cyclist and the difficulties of the course. The rear derailleur is responsible for the change of gables (or speeds). Unlike the track bike (only one speed and a single tray) there can be on a road bike up to 11 pinions and the rear derailleur has the role of moving the chain from one to the other.
