Let f : R <span l

Answer :

Formula:-


(i)A function f : X Y is defined to be invertible, if there exists a function g : Y X


such that gof =Ix and fog = Iy .The function g is called the inverse of f and is denoted by f-1


(II)Let f : AB and g : BC be two functions.


Then, the composition of f and g, denoted by g o f, is defined as the function g o f : AC


given by g o f (x) = g (f (x))


Given:-


(i)f : R R



F(y)=x



2y-3-4x=0
