Please note the scale of the axis.

• (-∞, 3]

• (-∞, ∞)

• [3, ∞)

• (-6, 3]

Is the relation shown a function?

• No, because not every input has a single output.

• Yes, because every input does has a single output.

• No, because every Y value is paired with an X value.

• Yes, because every Y value is paired with an X value.

Is the relation shown in the mapping a function?

• Yes, every Y value is paired with an X value.

• Yes, because every input is paired with exactly one output.

• No, not every Y value is pared once.

• No, because not every input is paired with exactly one output.
