Relations v.s Functions

What is the range of the table?

• {-4, 0, 1, 3}
• {-2, 0, 2, 3}
• {-4, -2, 0, 1, 2, 3}
• { (0, 0), (2, -4), (3, 3), (-2, 1) }

What is the domain of the graph?

• {-4, -2, -2, 1, 1, 3}
• {-4, -2, -2, 1, 3}
• {-2, 1}
• {-4, -2, 1, 3}

State the domain of the relation. Write it in set notation.
{(8, 5), (-6,-9), (2, 5), (0, -8)}

• {(8, 5), (-6,-9), (2, 5), (0, -8)}
• {-6, 0, 2, 8}
• {-9, -8, 5}
• 8 -6 2 0

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.
