Representing Relations

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) }

State the range of the relation.

{ (3, -2) , (4, -3), (5, -4), (6, 0) }

• (3, -2, 4, -3)

• (-2, -3, -4, 0)

• {-4, -3, -2, 0 }

• { 3, 4, 5, 6 }

Is this a function?

• Yes, because all inputs have one output

• No, because 40 has two inputs

• Yes, because all outputs have one input

• No, because 2 has two outputs

Is this a function?

• Yes, because all inputs have one output

• No, because 30 has two inputs

• Yes, because all outputs have one input

• No, because the lines are not straight across
