Answer: OPTION D

Step-by-step explanation:

Given the functions $f(x) = x^2 - 2x + 9$ and $g(x) = 8 - x$ , you need to substitute the function g(x) into the function f(x), then:

$(fog)(x)=(8-x)^2 - 2(8-x) + 9$

Now, you need substitute the input value $x=-4$ into $(fog)(x)$ , then you get the following output value:

$(fog)(-4)=(8-(-4))^2 - 2(8-(-4)) + 9$

$(fog)(x)=(8+4)^2 - 2(8+4) + 9$

$(fog)(x)=(12)^2 - 2(12) + 9$

$(fog)(x)=129$

This matchis with the option D
