    MHB Proving (fοg)(x) = 3f(x) for f(x)=log(1+x)/(1-x) and g(x)=(3x+x2)/(3x2+1)

    thank you so much :)

    MHB Proving (fοg)(x) = 3f(x) for f(x)=log(1+x)/(1-x) and g(x)=(3x+x2)/(3x2+1)

    f(x)=log(1+x)/(1-x) and g(x)=(3x+x2)/(3x2+1) prove that (fοg)(x)=3f(x)

    MHB What is the result of three compositions of the function f at -1?

    IF f(X)={x2, X>3 ; 3X+4, 0<X<3 ; X3+2 , X<0 } find (f°f°f)(-1) p.s the answer is 49! i don't know how this f(x) includes three terms x2 , 3x+4 and x3+2 And which term i need to use for the (f°f°f)(-1)
