Why does it need additional biasing resistor apart from the emitter resistor? The emitter resistor and the base voltage determines the bias current, IE.

I am refering to emitter resistor RE4
in fig 6.78........... I was asking why we can't use voltage divider biasing in emitter follower in fig 6.78
But i think what buddypoor said, makes sense.
So is the operating point of emitter follower in fig 6.78 is being set by gain stage ???
