CCSS.8.F.A.1

What is the range of the following relation:

{(9, -2), (4, 3), ( 8, 10), ( -4, 8)}

• {-4, 4, 8, 9}

• {-2, 3, 8, 10}

• {9, -2, 4, 3}

• {8, 10, -4, 8}

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}

Which of the following relations describes a function?

• {(0,0), (1,-1), (1,1), (2,2)}

• {(-2,2), (-1,1), (1,1), (2,2)}

• {(-1,0), (0,1), (1,0), (0,-1)}

• {-2,2), (-1,-1), (-1,1), (0,0)}

Given the relation {(2, 3) , (-5, 2) , (6, -5) , (0,3), (-1, 0)}, which point would make the relation not a function if it were added.

• (1, 0)

• (-2, 3)

• (4, -5)

• (0, -1)
