Answer:

This relationship is a function

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.


x = -4,\ y = 3\\\\x = -1,\ y = 1\\\\x = -2,\ y = 5\\\\x = 3,\ y = 7

Therefore this relationship is a function
