Question

Given A = {(1, 3)(-1, 5)(6,4)}, B = {(2,0)(4, 6)(-4,5)(0, 0)) and C = {(1, 1)(0, 2)(0, 3)(0, 4)(-3,5)}, answer the following multiple

choice question:
From the list of sets A, B, and C, state the domain of set B.
Domain of set B: {0, 6,5}
Domain of set B: {2, 4,-4, 0}
Set B does not have a domain

Answer 1

"Domain of set B: {2, 4,-4, 0}"

Explanation:

When it the set A,B,C (and others) are given in this form it means that the coordinate pairs are the domain and range of each set, respectively.

The first coordinate is part of the domain (x) and the second coordinate is part of the range (y).

For example, the domain of A is all the numbers that are the first in each coordinate pair, so domain of A would be 1, -1, and 6.

Likewise, the domain of B would be 2, 4, -4, and 0.

Hence,

Domain of set B: {2, 4,-4, 0} -- is the correct answer.
