Continuous Domain and Range

On a graph, how is the inequality "less than or equal to" represented?

• An open circle.

• A dashed line.

• A closed circle.

• A dotted line.

How is the domain and range of a continuous relation typically written?

• A list of numbers.

• As an inequality.

• Using a mapping diagram.

• As ordered pairs.

If a continuous relation has only one endpoint (like a ray), how many inequality signs are needed to write its domain and range?

• Zero.

• One.

• Two.

• Three.

What is the domain of the continuous relation shown in the graph?

• -4 < x < 5

• -4 ≤ x < 5

• -4 < x ≤ 5

• -4 ≤ x ≤ 5

What is the range of the continuous relation shown in the graph?

• y > -5

• y < -5

• y ≥ -5

• y ≤ -5
