Need help with questions 3 and 5. Answers only is fine. I'll give helpful rating. Thanks!

Select the correct answer. Given the function x) = x2 + 13.5X+ 45, use Newton's Method to find X5 when x0 = -7. O A. -8 O B. -7 5 O C. -7 Select the correct answer. Identify the reason Newton's Method fails for the function x) = 3X3 6X+ 7, where 'x_0 = ((2)/(3))'\\(('|)/(2))'. O A. non-converging iterations O B. wrong initial approximation 0 c. f'(X) = o O D. none of the above
