For which pairs of functions is (fog)(x)=x?

f(x) = x2 and g(x) = 1/x

f(x) = 2/x and g(x) = 2/x

f(x) = x-2/3 and g(x) = 2-3x

f(x) = 1/2 x-2 and g(x) = 1/2 x+2

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
