It is known that f (x) is an odd function defined on (- ∞, + ∞), and f (x) is a decreasing function on [0, + ∞) A. f（5）＞f（-5）B. f（4）＞f（3）C. f（-2）＞f（2）D. f（-8）=f（8）

∵ odd function f (x) is a decreasing function on [0, + ∞), and ∵ f (x) is also a decreasing function on (- ∞, 0). ∵ f (x) is a decreasing function on [0, + ∞), and ∵ f (2) < f (0) = 0, and f (4) < f (3), it is incorrect to get B; similarly, we can get f (- 2) > F (0) = 0, so we can get f (- 2) > 0 > F (...)
