Use the graph of the function f(x) to locate the local extrema and identify the intervals where the function is concave up and concave down.

A. Local minimum at x = 3; local maximum at x = -3 ; concave up on (0, -3) and (3, ?); concave down on (-3, 3)
B. Local minimum at x = 3; local maximum at x = -3 ; concave up on (0, ?); concave down on (-?, 0)
C. Local maximum at x = 3; local minimum at x = -3 ; concave up on (0, -3) and (3, ?); concave down on (-3, 3)
D. Local minimum at x = 3; local maximum at x = -3 ; concave down on (0, ?); concave up on (-?, 0)
