For the function f(x) = –2(x + 3)2 − 1, identify the vertex, domain, and range.
The vertex is (3, –1), the domain is all real numbers, and the range is y ≥ –1.
The vertex is (3, –1), the domain is all real numbers, and the range is y ≤ –1.
The vertex is (–3, –1), the domain is all real numbers, and the range is y ≤ –1.
The vertex is (–3, –1), the domain is all real numbers, and the range is y ≥ –1.
