The resistor(Rf) from the output to inverting(V-) terminal on both these op amps make them inverting. Each have a gain of -10 V/V ( -Rf/Rin = -10K /1k). There is a resistor divider that divides Vgen by 2. The voltage seen by the first op amp is Vgen/2. This divider was made since sometimes the output would be too high for lab testing with required Vgen input.
