3-71.

Find the domain and range for each of the relations graphed below.

  1. A 4 quadrant coordinate plane with  3 points: (0, comma 1), (1, comma 0), and (2, comma negative 2).

    Look in your notes, the glossary, or the index for definitions and examples of domain and range.

    Domain:
    Range:

  1. A 4 quadrant coordinate plane with a line segment with closed end points at (negative 1, comma negative 1) and (1 comma 2).

    See (a).

    Domain:
    Range:

  1. A 4 quadrant coordinate plane with a ray starting with an open circle at (negative 1, comma negative 1) and going up and left through the point (negative 2, comma 2). There is also a line segment from the point with a closed circle at (negative 1, comma negative 2) to the point with a closed circle at (2, comma negative 1).

    Domain:
    Range:

  1. A 4 quadrant coordinate plane with  2 rays, each starting at the point (negative 1, comma negative 1). The left ray goes up and left through the point (negative 2, comma 1). The right ray goes up and right through the point (1 comma 2).
