Use the conv command to carry out the following multiplication of polynomials,
(x + 1.4) (x – 0.4) (x +0.6) (x – 1.4). Plot the product for –1.5 < x < 1.5
After you have finished all the plotting and text cmds for p04, use the cmd
savefig(p04fig, 'p04fig.fig'); % to save figure p04fig as file named p04fig.fig
Use the polyder and roots cmds to find the maxima and minima of the given polynomial
and then add a plot of the maxima and minima that matches the example output.
Note: the order of legend entries follows the same order as the plot cmds you use.
Note: the 2nd derivative can be used to determine if a root is a minima or maxim
Hint: maxima have values at the 2nd derivative that are negative
Hint: minima have values at the 2nd derivative that are positive
