Functions and Domain/Range

Does this table represent a function?

• Yes!

• No!

Give the range of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)

• {2, 9, 7, -8}

• {11, -3, 21, 6}

• -8 < x < 9

• -3 < y < 21

What is the range of the function?

• [-1, ∞)

• (-1,1)

• (-1, ∞)

• (-∞, ∞)

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.
