Impedance and frequencies

In the circuit shown in Figure P6.9 (in the attached file), if
L = 190 mH
R1 = 2.3 kΩ
R2 = 1.1 kΩ
C = 55 nF

a) Determine how the input impedance behaves at extremely high or low frequencies.
b) Find an expression for the input impedance in the form (see attached file)
c) Determine the four frequencies at which f1(w) = +1 or -1 and f2(w) = +1 or -1.
d) Plot the impedance (magnitude and phase) versus frequency.
