x². - 16x + 63 Is f(x) = differentiable at x = 9? Justify your answer. x-9 Choose the correct answer below. O A. No, the function is not differentiable because f'(x) = 0 at x = 9. O B. Yes, the function is differentiable because f(x) is not continuous at x = 9. C. No, the function is not differentiable because f(x) is not continuous at x = 9. O D. Yes, the function is differentiable because f(x) is continuous at x = 9.
