To determine whether the relation is a function, we need to analyze the sets of ordered pairs and check the definition of a function: A relation is a function if every element in the domain corresponds to exactly one element in the range.
Given the available responses:
-
"This is a function because each domain has one range." - This is correct if the relation is indeed a function.
-
"This is a function because each range has one domain." - This is incorrect; a function does not require each range value to have only one associated domain value.
-
"This is not a function because the domain of -2 has more than one range." - This is correct if -2 indeed corresponds to multiple range values.
-
"This is not a function because the range of 1 has more than one domain." - This is incorrect; a function only concerns the uniqueness in the domain, not the range.
If the relation indeed has a case where a single domain value (like -2) corresponds to more than one range value, the correct answer would be the third option: "This is not a function because the domain of -2 has more than one range."
If you could provide the specific relation you're analyzing, I could give you a more precise answer.
