Option 1 gives you the condition :
y - 2 > 0 or y > 2
Option 2 gives two answers
-8 and 14.
Combining both we get 14.
Hence C

But mod (x2-4) can be negative when x2 is less than 4 for example when x is =0 or 1, x2-4 may have negative values as well, isn't it??gmatguy16 wrote:but when you combine 1 and 2 you realize that y cannot be negative,it has to be positive..so only only value for y .answer should be c
