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}

What is a function?

• A special relation in which each member of the range is paired with exactly 1 member of the domain.

• A special relation in which each member of the domain is paired with 2 members of the range.

• A special relation in which each member of the domain is paired with 3 members of the range.

• A special relation in which each member of the domain is paired with exactly 1 member of the range.
