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}

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Is this relation a function?

• Function

• Not a Function
