Question

What is the domain and range of {(2,-3),(4,6),(3,-1),(6,6), (2,3)} ?

Answer 1

In the set of ordered pairs {(2, -3), (4, 6), (3, -1), (6, 6). (2, 3)}:

The Domain is the set of the first number in every pair (those are the x-coordinates): {2, 3, 4, 6}.

The Range is the set of the second number of all the pairs (those are the y-coordinates): {-3, -1, 3, 6}.
