How do I approach this question? *69. Suppose that f'(x) > 0 and that f(a) < 0 while f(6) > 0, so that f(x) = 0 has a root r in the interval (a,b). Newton's method for finding r, starting at c in (a, b) is as follows: let Xo = c, and for n> 1, define In = In-1 - f(xn-1)/f'(xn-1). a) Taking f(x) = x – 23, a=-1/13, b=1/13 and xo = 1/V5 find x0, 11,x2,.... b) If...
