Answer:
The coordinates of the vertex of parabola are (-2,-9).
Step-by-step explanation:
The given function is
The vertex of a parabola lies on its axis of symmetry. Since the axis of symmetry is x=-2, tt means the x-coordinate of vertex is -2.
Let the vertex of parabola is (-2,y).
Substitute x=-2 in the given function to find the y-coordinate of vertex.
Therefore the coordinates of the vertex of parabola are (-2,-9).

Answer:
As x goes to negative infinity, g(x) goes to zero.
As x goes to positive infinity, g(x) goes to zero.
(So the answer is the second option)
Step-by-step explanation:
We have the function
First, let's look at what happens when we input smaller and smaller numbers
As we can see, as we input smaller and smaller numbers, the answer gets smaller.
Eventually, these fractions will be so small that they will get closer and closer to zero.
This same thing applies to larger and larger numbers, so the end behavior of each side will both be zero.
