How to find the transfer function of an inverting op-amp?

justme tells you exactly why \$R_a\$ doesn't matter. For the circuit, as shown, there is no current in \$R_a\$. So there is no voltage drop across it. So the output ...

How to find the transfer function of an inverting op-amp?

There is no load, so there is no current through Ra, so drop over Ra is zero.

How does an AC signal in a Transistor Amplifier Circuit swing output voltage if it is going below 0.7V?

Yes, your analysis is correct. That particular amplifier can't handle a 2 Vpp input signal without "clipping". That's the name of the effect that occurs when the transistor is driven into ...
