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
(0,2),(1,4), (2,5), (3,6)
We see that each value x has only a value of y.
[tex]x = 0,\ y = 2\\\\x = 1,\ y = 4\\\\x = 2,\ y = 5\\\\x = 3,\ y = 6[/tex]
Therefore this relationship is a function
