Question

How do you find the domain and range of (1, -2), (0,2), (-1, 6), (-2, 10)?

Answer 1

In the set of ordered pairs {(1, -2), (0, 2), (-1, 6), (-2, 10)},

The Domain is the set of the first number in every pair (those are the x-coordinates): {1, 0, -1, -2}.

The Range is the set of the second number of all the pairs (those are the y-coordinates): {-2, 2, 6, 10}.
