Suppose f has a continuous derivative whose values are given in the following table.
(a) Estimate the x-coordinates of critical points of f for 0 ≤ x ≤ 10.
(b) For each critical point, indicate if it is a local maximum of f, local minimum, or neither.

x 0 1 2 1 f'(x) 5 2 3 4 -2 -5 5 -3 6 7 8 9 2 3 1 10 -1
