For all the questions below, plot your figures within the window of ? = [−5, 5]. Remember, all your answers must be on a single file and your script must be self-sufficient and run without any errorsto receive any points. You should produce one figure for each question, two figures in total. Do not plot anything that you are not instructed to do so within this document.?[?] = ?(?[?] − ?[? − 8])?[?] = cos(2??)Question 1 (50 points). Plot the signals ?[?] and ?[?] defined above on a single figure using MATLAB. ?[?] should be traced in red and ?[?] should be traced in blue. Label all the axis, signals and the figure accordingly. Do not forget about the plotting window defined on top, ? = [−5, 5]. When you run your script, it should automatically display the required figure. See the following documentation for detailed explanation of how to plot discrete signals using MATLAB, as well as the MATLAB resources provided in the syllabus: https://www.mathworks.com/help/matlab/ref/stem.htm…https://www.mathworks.com/help/matlab/creating_plo…Question 2 (50 points). Plot the signal ?[?] defined below. Label all the axis, signals and the figure accordingly. Do not forget about the plotting window defined on top, ? = [−5, 5].
