If `f(x) =(ax-b)/(bx-a)=y`
Find the value of f(y).

If f(x)=(ax-b)/(bx-a) , then find the value of f(1/x) .

If y=f(x)=(ax-b)/(bx-a) , the prove that : x=f(y)

If y=f(x)=(ax-b)/(bx-a) , the prove that : x=f(y)

If f(x)= y = (ax-b)/(cx-a) , then prove that f(y) = x

If f(x + y) = f(x) +f(y), then the value of f(0)

y=f(x)=(ax-b)/(cx-a) then f(y)=?

If y= f(x) =(ax-b)/(bx-a) , prove that f(y) =x.

(i) If y = f(x) = (3x-1)/(5x-3) , prove that f(y) = x (ii) If y = f(x) = (ax -b)/(bx-a) , prove that f(y) = x

If f(X) = (ax-b)/(bx-a) , show that f(f(x)) = x
