Question

What is the DOMAIN of the given set? {(-10,9), (-5,13), (0,17), (5,21), (10,25)}

A) (-10, 9,-5, 13, 0)
B) {-10,-5, 0, 5, 10)
C) (9, 13, 17, 21, 25)
D) {17,5, 21, 10, 25)

Answer 1

The domain of the given set of ordered pairs is the set of the first elements from each pair, which is {-10,-5, 0, 5, 10}.

Step-by-step explanation:

The domain of a set of ordered pairs is the set of all the first elements of each pair. Looking at the given set {(-10,9), (-5,13), (0,17), (5,21), (10,25)}, the domain comprises the first numbers in each ordered pair.

These first elements are -10, -5, 0, 5, and 10. Therefore, the domain of the given set is represented as a set of these elements, which is option B: {-10,-5, 0, 5, 10}.
