Answer:
A. F(x) = 1/(x +2)²
Explanation:
The asymptote at x = -2 tells you that x -(-2) = x +2 is a denominator factor. The fact that the function has the same sign on both sides of the asymptote tells you that factor has even degree.
Of the choices listed, the appropriate one is ...
F(x) = 1/(x +2)²
