Question 576010
f(x) = 4x


f(g(x)) = 4(g(x))


f(g(x)) = 4((1/4x)


f(g(x)) = (4*1/4)x


f(g(x)) = (4/4)x


f(g(x)) = 1*x


f(g(x)) = x


(f o g)(x) = x

--------------------------------------------


g(x) = (1/4)x


g(f(x)) = (1/4)(f(x))


g(f(x)) = (1/4)(4x)


g(f(x)) = ((1/4)*4)(x)


g(f(x)) = (4/4)x


g(f(x)) = 1*x


g(f(x)) = x


(g o f)(x) = x
