Question

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

Answer 1

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

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

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]

$y\leq -1$
