is a valid argument
is not a valid argument
For the first argument: 
From the definition of absolute value function
if 
That is every positive number is its own absolute value. Since
,
we can argue that
so the first argument is valid
For the second argument: 
From the definition of absolute value function

This means that

or

no part of the definition allow for the option
. So the second argument is not valid.
