% Load the response data
load responseData frequency magnitude

% Create an x-axis semilog plot using the semilogx function
figure
semilogx(frequency, magnitude)

% Set the axis limits and turn on the grid
axis([min(frequency) max(frequency) -6.5 6.5])
grid on

% Add title and axis labels
title('Magnitude Response (dB)')
xlabel('Frequency (kHz)')
