Answer: Domain = [-4, ∞) Range = [-1, ∞)

Explanation:

Domain represents all of the x-values in the graph.

The smallest x-value is -4.

The biggest x-value is infinity (see the arrow on the far right line)

Interval notation is: [-4, ∞).

NOTE: -4 has a bracket because it is an included value (closed dot)

Range represents all of the y-values in the graph.

The smallest y-value is -1.

The biggest x-value is infinity (see the arrow on the far right line)

Interval notation is: [-1, ∞).

NOTE: -1 has a bracket because it is an included value (closed dot in at least one place on the line)
