Question

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.

Answer 1

\[f(x)=-2(x+3)^2-1\] is written in vertex form
\[f(x)=a(x-h)^2+k\] where the vertex is \((h,k)\)

Answer 2

so a?lol

Answer 3

no not A
