If f(x) = `(1+x)/(1-x)` then `f(x) . f(x^2)/ (1 +(f(x))^2)`

If f(x) = (x+2)/(3x-1) then f (f(x)) is

If f(x) = (1 + x)/(1 - x) Prove that ((f(x) f(x^(2)))/(1 + [f(x)]^(2))) = (1)/(2)

IF f(x) = ( x+2)/(3x-1) , then f(f(x)) is

If f(x)=log((1+x)/(1-x)), then (a) f(x_(1))f(x)=f(x_(1)+x_(2))(b)f(x+2)-2f(x+1)+f(x)=0 (c) f(x)+f(x+1)=f(x^(2)+x)(d)f(x_(1))+f(x_(2))=f((x_(1)+x_(2))/(1+x_(1)x_(2)))

If f (x) = (x +2)/( 3x -1) , then f {f (x) } is

If f(x)=(x)/(1-x);x!=1 then f^(100)(x) is [where (fof (x)=f^(2)(x)]

If f(x)=log((1+x)/(1-x)),t h e n (a) f(x_1)f(x_2)=f(x_1+x_2) (b) f(x+2)-2f(x+1)+f(x)=0 (c) f(x)+f(x+1)=f(x^2+x) (d) f(x_1)+f(x_2)=f((x_1+x_2)/(1+x_1x_2))

If f(x)=log((1+x)/(1-x)),t h e n (a) f(x_1)f(x_2)=f(x_1+x_2) (b) f(x+2)-2f(x+1)+f(x)=0 (c) f(x)+f(x+1)=f(x^2+x) (d) f(x_1)+f(x_2)=f((x_1+x_2)/(1+x_1x_2))

If f(x)=log((1+x)/(1-x)), then f(x) is (i) Even Function (ii) f(x_(1))-f(x_(2))=f(x_(1)+x_(2)) (iii) ((f(x_(1)))/(f(x_(2))))=f(x_(1)-x_(2)) (iv) Odd function

If f(x) = 2/(2-x) then show that f(f(f(x))) = (2(x-1))/x
