2 answers:
Answer:
The correct option is A.
Step-by-step explanation:
The vertex form of an absolute function is
Where, (h,k) is vertex.
Domain is the set of input values.
The given function is
It is the vertex from of an absolute function. Here h=-4 and k=1, so the vertex of the function is (-4,1).
These functions are defined for all real values of x. So, the domain of the given absolute function is all real numbers
Therefore the correct option is A.

To find the mean, you have to add all the numbers then divide it by how many numbers there are.
In this case, you'll need to add all those numbers and divide it by 4.
The mean is 1995.
