When is it convenient to use semilogx,or semilogy, or loglog on matlab?

Question 14 Correct Mark 4 out of 4 P Flag question The following script generates a figure with four subplots: The transistor density (the number of transistors that fi t per square inch) on a semiconductor integrated circuit double s every two years. Transistor density was 2300 in the year 1971 year 1971:2:2011; density2300*2. ( (year-1971)/2); subplot (2,2,1); % plot plot (year,density); subplot (2,2,2); % semilogx semilogx (year,density); subplot (2, 2, 3) ; % semi logy semilogy (year,density); subplot (2,2,4); % loglog loglog (year,density) To display a linear graph, which is the best approach? Select one: cross out a. plot cross out semilogx C. semi logy d·loglog e, None of them would be linear cross out cross out cross out

Answer)
loglog in matlab plots the columns of the metric as y (loglog(y)) versus their index if y contains reals numbers. semilogx is the plot for logarithmic scales for x-axis and semilogy is the plot for logarithmic scales for y-axis in Matlab. As in the above question image, we see 3 types of plots as:
semilogx(year, density);
semilogy(year, density);
loglog(year, density);

In loglog(year, density); we plot all the density versus year pairs.
In semilogx(year, density); , we plot by using a base of 10 logarithmic scale for the x-axis and a linear for the y-axis.
In semilogy(year, density);, we plot the base 10 logarithmic scale for the y-axis versus linear scale for the x-axis.
