Using MATLAB, Given the function g(x) as shown below:

g(x) = x4-7x3+8x+2

1) Find the value of the polynomial at x=2

2) Find the value of the polynomial at x = [2 4 5 7]

3) Find the roots of the polynomial

4) Integrate the polynomial with an integration constant of 5, plot it on a 2D line plot for x in the range -1 and 6.
