Answer:

  1. D: {-1, 0, 1, 4}; R: {-6, 3, 5, 7}
  2. D: {-1, 2, 3}; R: {3, 5, 7}
  3. D: {-2, -1, 0, 1}; R: {0, 1, 4}

Step-by-step explanation:

For relations expressed as (input, output) or (x, y) pairs, the domain is the list of inputs, or x-values. The range is the list of outputs, or y-values. Yes, it is that simple. (We often like to arrange the lists in increasing order.)

1. Domain: {-1, 0, 1, 4}

  Range: {-6, 3, 5, 7}

2. Domain: {-1, 2, 3}

  Range: {3, 5, 7}

3. Domain: {-2, -1, 0, 1}

  Range: {0, 1, 4}
