1. The problem statement, all variables and given/known data Identify the formula xn+1 = -2xn + 3yxn^(2/3) as the Newton's method for a certain function. Here y is a fixed constant. What is the limit of xn? 2. Relevant equations Newton's method?: xn+1 = xn - f(xn)/f'(xn) 3. The attempt at a solution I don't know how to begin. Thanks in advance!
