**Jai**, Wednesday, August 7, 2013 at 11:46pmNote that is only possible if x is any real number less than or equal to zero:

x <= 0

Therefore, the answer is [D] Nonpositive.

Note nonpositive is different from negative numbers, as nonpositive includes zero, while Negative numbers does not include zero. (Zero is neither positive or negative number)

Hope this helps~ :)

|x| = x if x >= 0

|x| = -x if x < 0

(C)

It happens that -0 = 0, but the definition of |x| specifies that |x|=x if x>=0
