d. f(x-k)=f(x)+k
i need my answer asap .
you get max amount of points i can give

B

Step-by-step explanation:

make 8 become k

you have f(x)= -x+k

now change -x+k to x-k because x is a negative

now you have f(x)=x-k

now make f(x) f(x-k) because you have to subtract k from both sides

now make x-k f(x)-k because you need to show work i can't explain this part online.
