I edited your post to make the image readable.

Have you done anything already? Are you supposed to use the Laplace Transform variable 's' for the Transfer Function?

If that's the case, keep in mind that \(Z_C=\frac1{sC}\) and \(Z_L=sL\), where Z is the impedance, C is the capacitance and L is the inductance.

Z1= 1/sC1 + sL1
Z2= (1/sC2)|| (sL2) = (sL2/sC2)/(1/sC2+sL2)
Z2= sL2 / (1+s^2L2C2)

using voltage divider rule

Vo = Vi * Z2/(Z1+Z2)

then transfer function is

T(s)=Vo(S)/Vi(s) = Z2/(Z1+Z2)

etc.

It is nice that you want to help a fellow student, but it's best if you don't give him the answer outright. Let him make an initial effort, in order to "earn" the answer.
