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).
