a$)$ Plot the polynomial $()=4-3\mathrm{.}53-2\mathrm{.}52+14-6$ from t $=-2\mathrm{.}5$ to $4.$ Use plot tools to

add a label on the x$-$axis, a label on the y$-$axis, a title, and a grid. Also change the color of

the graph to something other than blue. Use the data cursor to estimate all of the roots of

the polynomial $($Look in the Moodle Handouts Topic area for the file "Finding the Root

of a Polynomial.pdf$"$ if you are unclear about what a 'root' is$.).$ Include your estimated

roots on your plot.

b$)$ Using good programming techniques create a script file $(.$m or $.$mlx$)$ for generating the

plot with all the same annotations are described in part a$).$ Submit through Moodle your

$.$fig file from part a$)$ as well as your script for automating the generation of the plot.
