interval notation
given the inequality, shade the set of numbers on a number line. write the set using interval notation.

1. \\(x < 10\\)
2. \\(x \ge -2.5\\)
3. \\(-8 < x < 2\\)
4. \\(x < 0\\) or \\(x > 10\\)

domain & range

• domain - set of xs, visually appearing left-to-right on graph
• range - set of ys, visually appearing bottom-to-top on graph

find the domain & range for each graph.

1. find the domain and range of the graph:
2. find the domain and range of the graph:

Explanation:

Determine the domain from the graph

$$ \text{Domain} = [-3, 4] $$

Determine the range from the graph

$$ \text{Range} = [-3, -1] $$

Answer:

1. Find the Domain and Range of the graph:

Domain = <blank>\([-3, 4]\)</blank>

Range = <blank>\([-3, -1]\)</blank>
