Answer:
Option A.
Explanation:
The parent function is the quadratic function, that is:

Function g:
The function g is the function f concave down, that is, -f.
Also, for the parent function, we have that y = 1 when x = 1. On the function g, otherwise, we have that when x = 1, y = -1/3. So:

The correct answer is given by option A.
