What is the domain of this function?
(2, 4), (5, 5), (8, 6), (11, 7)

• {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11)
• {2, 5, 8, 11}
• {4, 5, 6, 7}

What is the range of the function?

• { -5, -2, 1, 4 }

• y > 3

• -5 ≤ y ≤ 4

• {3}

What is the domain of the function?

• { -5, -1, 1, 5 }

• {-1, 1, 2, 4 }

• -1 ≤ x ≤ 4

• -5 ≤ y ≤ 5

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.
