For the function f(x) = -2(x + 3)^2 -1, identify the vertex, domain, and range. a.) the vertex is (3, -1), the domain is all real numbers, and the range is y ≥ -1. b.) the vertex is (3, -1), the domain is all real numbers, and the range is y ≤ -1. c.) the vertex is (-3, -1), the domain is all real numbers, and the range is y ≤ -1. d.) the vertex is (-3, -1), the domain is all real numbers, and the range is y ≥ -1
