The resistors establish the quiescent or Q-point. It is about this point that an AC signal can be amplified. This Q-point is located in the transistor's linear range, not in either cutoff or saturation. You could of course use batteries or DC power supplies, but resistors is way more convenient.

thanx papabravo

 

Biasing of transistors is taught in high school. Don't you go to school??
