is the relation a function? why or why not?
o yes, because each x - value has only one y - value paired with it.
o no, because each x - value has only one y - value paired with it.
o yes, because the x - value 11 has two y - values paired with it.
o no, because the x - value 11 has two y - values pair with it.

Explanation:

A function is defined as a relation where each input (x - value) has exactly one output (y - value). In the given relation, the x - value 11 is paired with two different y - values (5 and 8). So, it does not meet the criteria of a function.

Answer:

No, because the x - value 11 has two y - values pair with it.
