Find all the roots to the third decimal place of the function using f(x)=x- 2x + ax+a Part I) one of the bracketing methods we have covered Part II) one of the open methods we have covered. Calculate until the approximate error is less than 0.001 or the number of iteration is no more than 100. Choose the initial guess(es) so that it takes more than 5 iterations to converge. Here, a = sum of your student ID/100. For example, for student ID = 123 456 789, a = (1+2+3+4+5+6+7+8+9)/100 = 0.45
