A root alpha of equation f(x) = 0 can be computed to any degree of accuracy if a 'good' initial approximation x0 is chosen for which
- A. f(x0) > 0
- B. f(x0) f''(x0) > 0
- C. f(x0) f''(x0) < 0
- D. f''(x0) > 0
Answer: B. f(x0) f''(x0) > 0
Explanation: Convergence of Newton-Raphson is guaranteed if f(x0) * f''(x0) > 0.
