If `f(x)=log.((1+x)/(1-x))` and `g(x)=(3x+x^(3))/(1+3x^(2))`, then find fog(x).

Given f(x)=log((1+x)/(1-x)) and g(x) = (3x+x^(3))/(1+3x^(2)) , then fog(x) is

Given f(x)=log_(10)((1+x)/(1-x)) and g(x)=(3x+x^(3))/(1+3x^(2)) , then fog(x) equals

If f(x)=log((1+x)/(1-x)) and g(x)=((3x+x^(3))/(1+3x^(2))) then f(g(x)) is equal to f(3x)(b)quad {f(x)}^(3) (c) 3f(x)(d)-f(x)

Given f(x)=log[((1+x))/((1-x))]andg(x)=((3x+x^(2)))/((1+3x^(2))) , then what is f[g(x)] equal to ?

If f(x)=log_(e)((1+x)/(1-x)),g(x)=(3x+x^(3))/(1+3x^(2))andgof(t)=g(f(t)) then what is g^(@)f((e-1)/(e+1)) equal to?

If f(x)=(x+2)/(x+1) and g(x)=(x-2)/(x), then find the domain of fog(x)

If f(x)=(x)/(sqrt(1-x^(2))),g(x)=(x)/(sqrt(1+x^(2))) then ( fog )(x)=
