Answer:

Domain #= { -3, 0, 1, 6}#
Range #= { 2, 3, 4 -6}#

Explanation:

Given the discrete relation
#color(white)("XXXX")##(x, y) epsilon {(-3,2), (0,3), (1, 4), (1, -6), (6, 4)}#

The Domain is the collection of values for #x#
and
The Range is the collection of values for #y#

(By the way, you might note that this relation is not a function, since #x=1# maps into 2 different #y# values).
