For the given relation:
the domain is:
D = {-6, 2, 6, 7}
The range is:
R = {-5, -4, -3, 0, 6}
How to determine the domain and range?
A relation maps elements from the domain into elements from the range, such that the general notation is (input, output).
So for a given relation, the domain is the set of the first values, and the range is the set of the second values.
Here we have:
{(-6, 6), (-6, -5), (2, -4), (6, -3), (7, 0)}
Then the domain is:
D = {-6, 2, 6, 7}
The range is:
R = {-5, -4, -3, 0, 6}
