Using MATLAB

. Consider the following polynomial: -x3 + 3x2 - 4 A. Plot the polynomial from x =-2 to 4 using a polynomial coefficient vector. Label the plot appropriately. B. Generate a similar plot using an anonymous function to represent the polynomial. C. Generate a similar plot using Symbolic Toolbox functions D. Estimate the (real) roots of the polynomial using one of your plots. E. Find the roots of the polynomial using the polynomial coefficient vector F. Find the roots of the polynomial using the Symbolic Toolbox in two different ways using solve and using factor
