Question

What is the domain and range for {(-3,2), (0,3), (1, 4), (1, -6), (6, 4)}?

Answer 1

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).
