Answer:
This relationship is a function
Step-by-step explanation:
By definition a relation is defined as a function if and only if for each input value x there is only one output value y.
In this case we observe the following ordered pairs
(-4,3),(-1,1),(-2,5),(3,7)
We see that each value x has only a value of y.
[tex]x = -4,\ y = 3\\\\x = -1,\ y = 1\\\\x = -2,\ y = 5\\\\x = 3,\ y = 7[/tex]
Therefore this relationship is a function
