Answer:

Domain: (-∞, ∞)

Range: [-1, ∞) or y ≥ -1

Explanation:

The domain is all x-values, or inputs, of the function. Here, it is all real numbers.

(-∞, ∞)

The range is all the possible y-values, or outputs, of the function. Here is it all numbers greater than -1, since the vertex is at -1.

[-1, ∞)
