The required function g(x) = -x²- 4. Option D is correct.
f(x) = x², g(x) to be determine with help of graph.
What is function?
Function is defined as y = f(x). For every x their is certain value of y.
Here, from the graph g(x) is reflection of f(x) at y = -4.
So g(x) = -f(x) - 4
negative sign for reflection.
g(x) = -x²-4
Thus, The required function g(x) = -x²- 4.
