Su 96 EGN 3420 EXAM 1 Name________________ Problem 1 (40 pts) Consider the function f(x) = x 3 - 4x 2 + 6x - 4. Fill in the tables below and stop when the true relative error falls below 15% or after the fifth iteration, whichever comes first. Retain the maximum number of digits in all intermediate calculations; however round all displayed results in the tables to 3 places after the decimal point. Show work for one iteration to receive partial credit! A. Bisection Method Iteration # x L x U x R | e T | , % 1 0.000 10.000 2 3 4 5 B. False Position Method Iteration # x L x U x R | e T | , % 1 0.000 3.000 2 3 4 5 C. Simple One Point Iteration
