For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range. (Hint: numbers should be listed smallest to largest)

• 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}

• {1, 2, 3, 4, 5}
• {-1, 1, 2, 3}
• {1, 2, 3, 5}
• [1, 5]
