CCSS.HSF.IF.A.1

What is the domain and range?

• D: {–3, 0, 7, 21} 
  R: {–2, 0, 3, 10}
• D: {–2, 0, 3, 10}
  R: {–3, 0, 7, 21}
• D: {–2, 3, 10}
  R: {–3, 7, 21}
• D: {3, 10, –2, 7, 21, –3}
  R: {0}

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}

Does this mapping diagram represent a function?

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