1. [6 points] The Newton method formula for finding the square root of a real number R from the equation x2 - R = 0 is: 3xt NIP A) Xit1 = B) Xit1 = NIP (xit D) Xi+1 = (3x; + R ) 2 C) Xit1 = Xi 2. [6 points] The next iterative value of the root of x2 - 4 = 0 using the Newton method, if the initial guess is 3, is: A) 1.5 B) 2.067 C) 2.167 D) 3.000
