Answer :

It is given that R be a function defined as f (x) = .

Let y be any element of Range f.

Then, there exists x ϵ R - such that y = f(x) 3xy + 4y = 4x

x(4 – 3y) = 4y

x = Let us define g: Range f R - as g(y) = Now, (gof)(x) = g(f(x)) = And, (fog)(y) = f(g(y)) = Therefore, gof = and fog = IRange f

Thus, g is the inverse of f

Therefore, The inverse of f is the map

: Range f R - , which is given by g(y) = Rate this question :
