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)
