is this a trick question?
anyway I use Matlab mostly and from my experience I'd say x range is [-3, 3] and y range is [-2, 2]. At least that's what I would set in the graph window given your curve...

Rule 1: Know the definitions!!

"range" MEANS the set of all y values of the function.

Looking at the graph I see that y goes up to 2, down to -2 and takes on all values between (the graph is a continuous line).

The range is the interval [-2,2] (i.e. all numbers larger than or equal to -2 and less than or equal to 2.)
