The answer is A
Explanation
It is given in the question that
![h(x) = (fog)(x) = x^2 -81](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%28fog%29%28x%29%20%3D%20x%5E2%20-81)
And ![x^2 -81](https://tex.z-dn.net/?f=x%5E2%20-81)
can also be written as
![(x^2 -40) -41](https://tex.z-dn.net/?f=%28x%5E2%20-40%29%20-41)
Therefore,
![(fog)(x) = (x^2 -40)-41](https://tex.z-dn.net/?f=%28fog%29%28x%29%20%3D%20%28x%5E2%20-40%29-41)
![f(g(x)) = (x^2 -40)-41](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20%28x%5E2%20-40%29-41)
That gives,
![g(x) = x^2 -40, f(x) = x-41](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E2%20-40%2C%20f%28x%29%20%3D%20x-41)
The coordinates of A is (-1, 2)
You just first move over to the left on the X axis making your x coordinate a negative. So when you you get to -1 you go up to where A is, which is at positive 2. Your y coordinate is positive because you're moving up on the Y axis and not down.
