If this exact question is repeatedly deleted, it's probably because of the ambiguity of the given equation. I see two likely interpretations, for instance:

or

If the first one is what you intended, then

and it follows that
2<em>k</em> + 8 = 3 ==> 2<em>k</em> = -5 ==> <em>k</em> = -5/2
If you meant the second one, then

which would give
<em>k</em> + 9 = 3 ==> <em>k</em> = -6
And for all I know, you might have meant some other alternative... When you can, you should include a picture of your problem.

Answer:
C
Step-by-step explanation:
X vertex = (0, - 3)
ax² + bx + c = y
0.x² + b.0 + c = - 3
c = - 3
Then:
The graphic of g(x) is the a one is negative, because the curve is below.
Then:
g(x) = - x² - 3
