CCSS.HSF.IF.B.5

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}
• D:{0, 1, 2, -4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D:{0, 1, 2, 3}
  R:{0, 1, 2, 3, 4}

Does this mapping diagram represent a function?

• No, because there are repeating input values
• Yes, because there are no repeating input values
