solve question 4

For the function: f(x) = 3x5 + 20x* - 10x3 - 240x2 250x + 200 2. Write a Matlab code for finding the roots of the function in iterative fashion using False-position and Newton-Raphson methods using the interval [-6,4). 3. For each method above, and for each root, what is the total number of iterations required to reach an absolute approximate error of 1E-8 and what is the corresponding root estimation and the function value at this root approximation? 4. For each method above, and for each root, plot the percent relative true error and the percent relative approximate error versus the number of iterations. 5. Comment on the relation between the errors from one iteration to the next for each root you find and compare/comment on the expected/unexpected efficiency and results of both methods
