CCSS.8.F.A.1

Identify the domain of the following relation:

• {-6, 14, 2, 38}

• (-6,14), (0,32), (2,38), (4,44)

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

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: {-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}
