Domain: ${5, 4, 3, 2}$ $color(green)({5,4,3,2})$
Range: ${- 7, 4, 2}$ $color(green)({-7,4,2})$

Explanation:

Given a set ${(x, y)}$ ${(x,y)}$
by definition
$XXX$ $color(white)("XXX")$ the Domain is the set of values for $x$ $x$
and
$XXX$ $color(white)("XXX")$ the Range is the set of values for $y$ $y$
