Let A=R-{2} and B=R-{1} if f:A rarr B is a function defined by f(x)=(x-1)/(x-2) show that f is one-one and onto. Hence find f^(-1) .

Let A = R - {2}, B = R - {1}. If f : ArarrB is a function defined by f(x) = (x-1)/(x-2) , show that f is one-one and onto.

Let A = R-{2} and B = R - {1}. If f : A rarr B is a function defined by f(x)= (x-1)/(x-2) then show that f is one-one and onto. Hence, find f^(-1) .

Let A =R- {2} and B=R - {1}. If f ArarrB is a function defined by f(x) = (x-1)/(x-2) , show that f is one -one and onto, hence find f^(-1)

Let A=R-{2} and B=R-{1}. If f:A rarr B is a mapping defined by f(x)=(x-1)/(x-2), show that f is bijective.

Let A = R- {3} and B = R- {1}. If f: ArarrB is a function defined by f(x)= (x-2)/(x-3) show that f is one -one and onto, hence find f^(-1) .

Let A=R-[2] and B=R-[1]. If f:A rarr B is a mapping defined by f(x)=(x-1)/(x-2), show that f is bijective.

If A=R-{3} and B=R-{1} and f:AtoB is a mapping defined by f(x)=(x-2)/(x-3) show that f is one-one onto function.
