3-22.

Determine the domain and range of each of the following graphs.

  1. Increasing curve, opening downward. Left side has arrow pointing down & left. Right side levels out below, y, = 1, with arrow pointing right.

    Are there any restrictions on what -values get used in this graph?
    Are there any restrictions on the -values that get used in this graph?

    Domain: All real numbers.
    Range:

  1. Increasing curve, opening downward, starting at the point (negative 3, comma negative 2), with arrow on right side, pointing up & right.

    The arrow indicates the graph continues in only one direction.

    Domain:
    Range:

  1. An upside down parabola where the vertex is at (4, comma 0).

    Domain: All real numbers.
    Range:

  1. A upward V with arrows at the ends of the V and a vertex at (3, comma negative 1).

    Domain: All real numbers.
    Range:
