Introduction to Functions and Relations

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}

What is the range?

• the set of all x-values

• the set of all y-values
