Given function $f(x)=log\frac{1+x}{1-x} and g(x)=\frac{3x+x^{2}}{1+3x^{2}}$ then (fog)(x)
1. -f(x) 2. f(x) 3. [f(x)]^{3} ^{4. None of these}
afterwards i am not able to simplify further
Sir u did a bit mistake. Mistakenly, u have taken numerator within log as 1 + (3x + 3x^{2})/(1 + 3x^{2}) but it is 1 + (3x + x^{2})/(1 + 3x^{2}).
