# What is the domain and range for {(1,2), (2,3), (2,5), (1,6)}?

In the set of ordered pairs {(-2, 0), (0, 6), (2, 12), (4, 18)}, the Domain is the set of the first number in every pair (those are the x-coordinates): {1, 2}.

The Range is the set of the second number of all the pairs (those are the y-coordinates): {2, 3, 5, 6}.

The domain of a function refers to the set of all possible input values (x-values), while the range refers to the set of all possible output values (y-values).

For the given set of points {(1,2), (2,3), (2,5), (1,6)}:

Domain: {1, 2} (The x-values of the points) Range: {2, 3, 5, 6} (The y-values of the points)

Therefore, the domain is {1, 2} and the range is {2, 3, 5, 6}.
