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, ∞)
