Answer
Domain = $-2,1,6$
Range = $-3, -1,5,8.$
Work Step by Step
The domain consists of all the $x$-coordinates of the ordered pairs:
$\{-2,1,6\}.$
The range consists of all the $y$-coordinates of the ordered pairs:
$\{-3, -1,5,8\}.$
The relation is graphed by plotting all the given ordered pairs as points.
A mapping diagram shows (with arrows) which output(s) are associated with the inputs.
