Answer:
Option C is correct.
Explanation:
We have been given the two graphs of the following function:

And g(x) we need to tell from the graph given.
We can see that the graph g(x) is downward parabola that means it has to have negative coefficient of x.
And shifting is 3 units down
So, from the graph of g(x)
g(x) will be:

Therefore, option C is correct.
