Domain #= {0, 2, 3, 5}#
Range #={-1, 0, 3, 7}#

Explanation:

Given a finite mapping of #xrarry# defined by the set
#(color(red)(x),color(blue)(y)) = {(color(red)(2),color(blue)(3)), (color(red)(3),color(blue)(7)), (color(red)(5),color(blue)(-1)), (color(red)(0),color(blue)(0))}#

The #color(red)("Domain")# is the set of values for #color(red)(x)#
and
the #color(blue)("Range")# is the set of values for #color(blue)(y)#
