3 Plotting (5*2=10 points) Plot the following functions in Matlab (make sure to have appropriate horizontal and vertical scales). 1. f(x) = 23 - 3x + 2, as a line plot on the domain ref-5,5). 2. f(x) = pr and f(x) = x2 on domain x (-1,1) on the same line plot (Hint: use "hold on" command) Include following features on both your plot: . Place a grid for the graph. (hint: grid on command) Put a legend for the graph. Ensure that the font size of the legend is 10. Label the x axis as 'Input Values'. Ensure the font size of the label is 10. Label the y axis as 'Value of the function'. Ensure the font size of the label is 10. Put an appropriate title for your graph. Ensure the font size is 10. . . As your submission, include both the MATLAB script and the plot taking screenshots of your code with the plot is ok, though it must be legible). 3 Plotting (5*2=10 points) Plot the following functions in Matlab (make sure to have appropriate horizontal and vertical scales). 1. f(x) = 23 - 3x + 2, as a line plot on the domain ref-5,5). 2. f(x) = pr and f(x) = x2 on domain x (-1,1) on the same line plot (Hint: use "hold on" command) Include following features on both your plot: .
