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.

    given the function y = (x-h)^2 + k the vertex is (h,k)

    read carefully if (x-h) = (x+3), what is h?

    nope, think carefully x - h = x + 3 subtract x from each side, what do you get?

    You divide it by negative h?

    right, so h = -3 and our vertex is (-3,-1)

    now, to find the range, we can see that the graph is a downward parabola, so our range is y <= -1
