Answer:
Domain of set of given ordered pair is { -1, 0, 5, 10}
Step-by-step explanation:
All of the values that can go into a relation or function (input) are called the domain.
The domain is the set of all first elements of ordered pairs (x-coordinates).
In the given question,
ordered pairs are (-1,1) , (0,-1) , (5,-11) , (10,-21)
Therefore,
Domain is the set of all first elements of ordered pairs.
i.e -1, 0, 5, 10
Hence the required set is { -1, 0, 5, 10}.
