I'm really confused on how to create this in MATLAB

A circuit that filters out a certain frequency is shown in the figure. In this filter, the ratio of the magnitudes of the voltages is given by: RV=ViVo=(L)2+(RR2LC)2R(12LC) where =2f, and f is the frequency of the input signal. Write a user-defined MATLAB function that calculates the ratio of magnitudes. For the function name and arguments, use RV= filtafreq (R,C,L,f). The input arguments are R the size of the resistor in (ohms); C, the size of the capacitor in F (farad); L, the inductance of the coil in H (henrys); and f, the frequency of the input signal in Hz (hertz). Write the function such that f can be a vector. Write a program in a script file that uses the filtafreq function to generate a figure with two plots of RV as a function of f for 10f100,000; Hz. In one plot C=160F,L= 45mH, and R=200, and in the second plot C and L are unchanged but R=50. The plot has a logarithmic scale on the horizontal axis. Label the axes and display a legend
