Problem 1) Find the root of the function (initial guess xi-0.5, xu 2.5), 400 f(y) 1 (3+y) By MATLAB: a) using the graphical method by inspection b) using "fzero" MATLAB function c) using the bisection method (also state the number of iteration) d) using the false position method (also state the number of iterations) e compare the results from c) and d), and then compare them with b) By hand f) the first 3 iterations using the bisection method g) the first 3 iterations using the false position method
