Answer:

Domain:

Interval notation: [-3, ∞)

or x ≥ -3

Range:

Interval notation: (-∞, ∞)

or

All real numbers.

Step-by-step explanation:

Domain:

Looking at the x values, we can see a vertex at x = -3. However, the graph continues onto x ⇒ ∞. Therefore, the domain would be:

Interval notation: [-3, ∞)

or x ≥ -3

Range: The range consists of values from y ⇒ -∞ to y⇒∞. Therefore:

Interval notation: (-∞, ∞)

or

All real numbers.

Answer:

Step-by-step explanation:

We see that the graph is defined on [-3, infinity) and for all y.

Thus, the domain is [-3, infinity) and the range is "all real numbers."
