Answer:
Last option: It is not a function because there are two different y-values for a single x-value.
Step-by-step explanation:
It is necessary to remember that, by definition, a relation is a function if each input value (x-value) has one and only one output value (x-value) .
In this case, the following points:
[tex](-2, -5), (- 1, 3), (1, -2), (3, 0), (4,- 2), (4, 4)[/tex]
You can observe that the input value 4 ([tex]x=4[/tex]) has two ouput values. These are:
[tex]y=-2\\\\ y=4[/tex]
Therefore, since there are two different y-values for a single x-value, you can conclude that the given graph is not a function.
