I think I have the correct answer choice, just not positive.

maddy1251 · Answer

Do you have some functions?

maddy1251 · Answer

When f(x) is f(2) it should equal 0, that is when you plug in '2' into your equaltion. e.g f(x)=x-2, so f(2)=2-2 = 0 . Only because it states x=0 when f(x)=f(2).

@Maddy1251  that's what I did

maddy1251 · Answer

@sammietaygreen all you gotta do is plug in the f(x) options into the equations.
