How to find transfer function.
The principle is quite simple, you have to determine the time constants of the circuit in two conditions: with a zeroed excitation you obtain the poles of the circuit and when the response is nulled you determine the zeroes of the transfer function. By inspection for instance, I can see there are no zeroes in your circuit, only poles.
