Front

Is the relation a function? Why? Options: Yes, because the x-value 11 has two y-values pair with it., Yes, because each x-value has only one y-value paired with it., No, because the x-value 11 has two y-values pair with it., No, because each x-value has only one y-value paired with it.

Back

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