Question

What is the domain and range of the relation: `{(5,-7),(4,4), (3,2), (2,-7)}`?

Answer 1

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

Explanation:

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