1-84.

What are the domain and the range for each of the following functions? Write your answers using inequality symbols if possible.

  1. Coordinate plane with points (negative 2, comma 0), (negative 1, comma 1), (2, comma negative 1).

    Which values (domain) and values (range) are a part in the points?

  1. Coordinate plane with line segment from (negative 1, comma 2) with open circle, to (1, comma negative 1), closed circle.

    Recall that open circles mean that the value is not included in the domain and range.

  1. Coordinate plane with ray, starting from (negative 1, comma negative 1) with opened circle and passing through the origin.

    D:
    R:

  1. Decreasing line, passing through the origin and the point (1, comma negative 1).

    What do arrows on both sides of a line indicate?
    Are there values it does not reach?
