Question

Is this relation a function?

{(1, 1)(2, 1)(3, 1)(4, 1)(5,1)}

A) Yes
B) No
C) Not enough information
D) It depends on the context

Answer 1

The relation is a function because each x-value is unique and maps to only one y-value, so the correct answer is A) Yes.

Step-by-step explanation:

To determine if a relation is a function, each x-value should map to only one y-value. In the given set {(1, 1), (2, 1), (3, 1), (4, 1), (5,1)}, each x-value is unique and maps to a single y-value. Therefore, this relation is indeed a function. The answer to the question is A) Yes.
