What is the purpose of a feedback resistor on an Op Amp

This is for a 741 inverting Op Amp. Thanks :)

-
It effectively lowers the gain of the op-amp to a usable level, by providing negative feedback.

-
The ratio of the feedback resistor and the input resistor sets the op-amp's gain.

-
The feedback and input resistors set the closed loop gain.
