Answer :
Answer:
Option C. The vertex is (-3, -1), the domain is all real numbers, and the range is y ≤ -1.
Step-by-step explanation:
we have
[tex]f(x)=-2(x+3)^2-1[/tex]
This is the equation of a vertical parabola written in vertex form open downward (the leading coefficient is negative)
The vertex represent a maximum
so
The vertex is the point (-3,-1)
The domain is all real numbers
The range is the interval (-∞,-1]
[tex]y\leq -1[/tex]
