Answer:
Domain:
Interval notation: [-3, ∞)
or x ≥ -3
Range:
Interval notation: (-∞, ∞)
or
All real numbers.
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.
