The domain of the following relation r {(3, -2), (1, 2), (-1, -4), (-1, 2)} is

Solution:

For an ordered pair (x, y) that a set contains:

x = domain, y = range

In relation, x can have 2 or more than 2 ranges.

So, domain = first element of the ordered pair

Given, ordered pair is r: {(3, -2), (1, 2), (-1, -4), (-1, 2)}

Domain = 3, 1, -1, -1

Since the element -1 is occuring twice, domain = {3, 1, -1}

Therefore, the domain is {3, 1, -1}.

The domain of the following relation r {(3, -2), (1, 2), (-1, -4), (-1, 2)} is

Summary:

The domain of the relation: r: {(3, -2), (1,2), (-1, -4), (-1, 2)} is {3, 1, -1}.
