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 and range of set B.

1. Domain of set B: {0, 6, 5}
2. Domain of set B: {2, 4, -4, 0}
3. Set B does not have a domain

Answer 1

Ok so the domain is our input or in other terms our x value
So lets go to our set B
Now our first element in set B is (2,0)
Our 2 is our x value and our o is our y value our output or in other words our range
So our Domain of Set B is every x value or first coordinate of every element in set B

Answer 2

Set B:
(2,0) our x value is 2
(4,6) our x-value is 4
(-4,5) our x value is -4
(0,0) our x value is our 0
So our domain for Set B is all the x values {2,4,-4,0}

Answer 3

Excellent! Thank you!
