1. Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not?

A. No, there is no value in the domain that corresponds to more than one value of the range.

B. Yes, the range value 3 corresponds to two domain values, 1 and 2.

C. No, the range value 3 corresponds to two domain values, 1 and 2.

D. Yes, there is no value in the domain that corresponds to more than one value of the range.

 I'm gonna go with letter A

Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not? No, the range value 3 corresponds to two domain values, 1 and 2. ... No, there is no value in the domain that corresponds to more than one value of the range.  Jun 13, 2017

Step-by-step explanation:  The answer is either letter B or letter D.

Determine if the relation is a function.

The relation is a function.

D

Step-by-step explanation:

We say a relation between two sets is a function if every value in the first set (the domain) corresponds to exactly one value in the second (the range). This doesn't mean we can't have two different domain values pointing to the same range value, but it does mean we can't have on domain value pointing to two different range values.

Our relation here is a function, since each domain value only points to one range value, so our answer is D.
