Using Matlab, include the code, a brief discussion of the code/logic, graphs and screenshots with results, and a brief analysis/discussion of the results.
Find the roots of the polynomial in question 1 above using the following methods and perform iterations until the approx. error becomes less than 0.01%. Also, comment on the accuracy and convergence rate of each method. a. Bisection method [10%] b. Simple fixed-point iteration method [10%] c. Newton-Raphson method [10%]
