Select the correct answer. (-1,1) (0,-1) (5,-11) (10,-21) What is the domain of the set of ordered pairs above? A. {-1, 0, 5, 10} B. {1, - 1, - 11, - 21} C. {-1, 10} D. {-1, 1}

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}.
