Extra exam question E7B10

WhyIn Figure E7-1, R1 and R2 provide voltage divider bias. In Figure E7-1, R1 (from the positive supply to the base) and R2 (from the base to ground) form a voltage divider that sets a stable DC voltage at the transistor's base, the standard voltage-divider bias arrangement used to establish a predictable operating point independent of the individual transistor's beta, answer B. They aren't load resistors, since the actual output load resistor is elsewhere in the circuit, and they don't function as self bias or feedback, those are separate roles filled by other components.
