Final answer:
The transfer function of the circuit is a constant value of 2 regardless of the frequency.
Step-by-step explanation:
The transfer function of a circuit relates the output voltage V2 to the input voltage V1 as a function of frequency. To calculate the transfer function, we need to determine the voltage ratio V2/V1 for different frequencies. From the provided information, we have V1 = 3 Hz and V2 = 6 Hz. Therefore, the transfer function is:
V2/V1 = 6/3 = 2
So, the transfer function of the circuit is a constant value of 2 regardless of the frequency.
