Explanation:

The range of a parabola that opens up starts at its vertex (1,−5)(1,-5) and extends to infinity.

Interval Notation:

[−5,∞)[-5,∞)

Set-Builder Notation:

y≥−5y≥-5

Determine the domain and range.

Domain: (−∞,∞),x∈R(-∞,∞),x∈ℝ

Range: [−5,∞),y≥−5

Answer and Step-by-step explanation:

Try putting a bracket ( ] ), so it looks like this:

(-infinity, -5]

this is because the -5 is included and that's where it stops.
