Question

{(4,-9)(6,6),(0,-9),(6,1)(4,9)}

What is the domain of the given set of points?

A) {0, 4, 6}
B) {1, 4, 6}
C) {4, 6}
D) {0, 1, 4, 6}

Answer 1

The domain of the given set of points, which are unique x-values from the ordered pairs, is {0, 4, 6}. Therefore, the correct answer is option A) {0, 4, 6}.

Step-by-step explanation:

The domain of a set of points refers to the set of all first coordinates (x-values) from the ordered pairs. The given set of points is {(4,-9), (6,6), (0,-9), (6,1), (4,9)}. To find the domain, we list the unique x-values from these points. The x-values are 4, 6, 0, and 6 (again, but it is already listed), and 4 (again, but it is already listed). The domain is therefore {0, 4, 6}.

Thus, the correct answer to the question "What is the domain of the given set of points?" is A) {0, 4, 6}.
