Question

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

Answer 1

Answer:

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.
