If `f(x)=(3x+2)/(5x-3)`, then `f[f(x)]` is equal to:

If f(x)=x^(3)+3x^(2)+3x , then f(x+1) is equal to

If f(x)=x+3, then f(x)+f(-x) is equal to

If f(x+3)=x^(2)-1, then f(x) is equal to

If f(x)=sqrt(x^(3)) , then f (3x) will be equal to

(2) If f(x)=x+(1)/(x) , then [f(x)]^(3)-f(x^(3)) is equal to

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

if f(x^(2))=4x^(6)+3x^(4), then f(5) is equal to
