For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range. (Remember - order matters and you don't write repeats!)

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D: {-4, 0, 1, 2}

  R:{-4, -3, 1}

• D: {0, 1, 2, 3, 4}

  R:{1, -3, -4}

• D: {0, 1, 2, -4}

  R: {1, -3, -4, 1}

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.
