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

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.
2.

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

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]

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
