A polynomial function has roots at-3,3,-1+4j.-1-4j. Determine the polynomial, plot the four roots in the complex plane, and plot the polynomial function for the range x = (-5,5) in steps of 0.01. You may wish to use help to look up the function poly, roots, and polyval. A polynomial function has roots at-3,3,-1+4j.-1-4j.
