Domain Range Discrete

Does this 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

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {-4, -3, 1}

  R: {-4, 0, 1, 2}

• D:{-4, 0, 1, 2}

  R:{-4, -3, 1}

• D:{0, 1, 2, 3, 4}

  R:{-4, -3, 1}

Identify the domain of the following relation:

• {-6, 14, 2, 28}

• {(-6,14), (0,32), (2,38), (4,44)}

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

What is the range?

• {-3, -1, 2, 4}

• {0, 4, 7}

• {0, 4, 4, 7}

• {-3, -1, 0, 2, 4, 7}
