2-66.

Using set notation, state the domain and range for each of the functions below.

Domain and Range

There are two accepted forms of notation for domain and range. Examine the graph at right. The domain and range of the function shown can be noted in either interval notation or in set notation.

Interval Notation: $D = [0, 1) \cup (1, ∞)$
$R = [1, ∞)$

Set Notation: $D = {x: x ≥ 0 \text{ and } x ≠ 1}$
