For the function f (x) = - 2 (x + 3) 2 - 1, identify the vertex, domain, and range. (2 poin

See below in bold.

Step-by-step explanation:

f (x) = - 2 (x + 3) ^2 - 1

Comparing this to the standard f (x) = a (x - b) ^2 + c where (b, c) is the vertex.

The vertex is (-3, - 1).

The domain is All real x.

The range is f (x) ≤ - 1.
