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

y=f(x)=(ax-b)/(bx-a), provethat f(y)=x

If y=f(x)=(ax+b)/(cx-a) , then find f(y).

Let f(x) = (ax+b)/(cx+d) . Then fof(x) = x , then

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

Let f(x) = (ax+b)/(cx + d), then f(x) has

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