If `A=[[1,2],[2,1]]` and `f(x)=(1+x)/(1-x)`, then f(A) is

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

If f(x)=x^2-2x+1 , then find f(1)

If f(x)=x^2+2x+1 , then: f(x-1)-=

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

If f'(x)=x-(1)/(x^(2)) and f(1)=(1)/(2) then find f(x).

If f(2x + 1 ) = x + 1 , then f(x^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) =log ((1+x)/(1-x)), then show that f(a)+f(b)=f ((a+b)/(1+ab)) and 2f(x)=f ((2x)/(1+x^2)).

If f(x)=(x+1)/(x-1) , then the value of f(f(2)) is
