If x = - |x| , then which one of the following statements could be true?
\(x = - |x|\)
The above equation means:
1. x can be ZERO
2. x can be any negative number
Now lets go the options.
I. x = 0 ===> Holds true based on point (1) above =====> TRUE
II. x < 0 ===> Holds true based on point (2) above =====> TRUE
III. x > 0 ===> Not True as value should either be ZERO or Less than ZERO =====> FALSE
Hence, the answer is D
