Hi,
For the first question, take the LCM and simplify.
Now put x=-x, You will see that after simplification – can be taken common from numberator and denominator and the same expression wil come. So function is even.
For the second question, Find the expression by putting x/(x-1) in place of x in F(x).
After simplification you will get FoG(x) = x.
So the function is y=x whoes inverse will be x only. So a is correct option.
