Find f'(0), f''(0), and determine whether f has a local minimum, local maximum, or neither at x=0. f(x)=2x-9x+7 What is f'(0)? f'(0) = What is f''(0)? f''(0) = | Does the function have a local minimum, a local maximum, or neither? A. The function has a local maximum at x=0. B. The function has a local minimum at x = 0. C. The function has neither a local minimum nor a local maximum at x = 0.
