2.1-2.4 Test Review

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: {-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}
