SOLVE USING PYTHON CODE. Given f(x) = 9x4 – 18x2 – 11. Use Newton’s method to find both the negative root and the positive root of f. Find intervals of positive initial guesses [c, d], where d > c > 0, for which Newton’s Method: (a) converges to the positive root, (b) converges to the negative root, (c) is defined, but does not converge to any root. Explain your answer.
