For the matrices in Exercises, perform each of the following tasks.

i Use the command p = poly(A) to find the characteristic polynomial.

ii Plot the characteristic polynomial p with the commands

and find the roots of the polynomial with r = roots (p).

iii Find the eigenvalues with e = eig(A) and compare the eigenvalues with the roots of the polynomial found in part (ii). Where are the eigenvalues located on the graph produced in part (ii)?
