How to code this in MATLAB

1. Use the function help or the on-line help in combination with MATLAB to familiarize yourself with the following MATLAB/Ocetave functions: plot, subplot, figure, print, set, get, semilogx, semilogy loglog, axis, box 2. Create plots of y(z) = z, y(z) = z2, y(z) = z3, y(z)-V(z), y(z) = e", and y(z) = log(z). 3. Generate and plot the following signal, z(t) = 10cm(2x5) + 0.5 cos(2x60). Use a sampling frequency = 12 times the maximum signal frequency. The sampling frequency is the inverse of the sampling period, f.-t Display the signal for 1 second and use the print command to generate a tiff figure. Use the hold on command and plot the samples of a(t)in the same plot (ie. as dots without linear interpolation). Explore the effect of reducing the sampling frequencyf, to f.-2fm where Jm corresponds to the maximum signal frequency
