Question

The domain of the following relation R {(6, −2), (1, 2), (−3, −4), (−3, 2)} is

{−3, −3, 1, 6}
{−4, −2, 2, 2}
{−4, −2, 2}
{−3, 1, 6}

Answer 1

The answer would be {-3, 1, 6}. This is because you wouldn't have to repeat the -3. The domain could also be known as x.

Answer 2

Option 4th is correct

the domain of the following relation R is:

`\{-3, 1, 6\}`

Explanation:

Domain is the set of all values of x-coordinates where function is defined.

Given the Relation:

`R = \{(6, -2), (1, 2), (-3, -4), (-3, 2)\}`

The ordered pairs are in the form of (x, y)

Domain = Set of all values of x.

In the given relation:

x-values = { 6, 1, -3}

⇒
`\text{Domain} = \{-3, 1, 6\}`

therefore, the domain of the following relation R is:

`\{-3, 1, 6\}`
