Note that when x  is any negative.....the expression will evaliuate to all values on  [ -2, 0)

 

When x = 0   the function evaluates to  0

 

When x is any positive.....the function evaluates to all values on  (0, 2]

 

This graph is continuous for all x

 

So  the range is  [ -2, 2 ]

 

Here's a graph :
