Determine which of the following relations is NOT a function.

• non-vertical linear graph.

• set of ordered pairs where an x term repeats.

• set of ordered pairs where a y term repeats.

• U-shaped graph.

Is the relation a function? Why.

• 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.
