Answer:

  1. D: [-4, 2]; R: [-2, 4]
  2. D: (-∞, 5]; R: [0, 0]
  3. D: [0, 5); R: [0, 7)
  4. D: (-∞, ∞); R: [0, ∞)

Step-by-step explanation:

The domain is the horizontal extent. The range is the vertical extent. An arrow on the end of the graph means it extends to infinity in the same direction. An open circle indicates a point that is not included in the graph. A square bracket in interval notation means the point is included in the interval; a round bracket (parenthesis) means the point is not included. By convention, infinity is indicated with a round bracket, because it is not a specific number.

1. D: [-4, 2]; R: [-2, 4]

2. D: (-∞, 5]; R: [0, 0]

3. D: [0, 5); R: [0, 7)

4. D: (-∞, ∞); R: [0, ∞)
