Question

if f(x)=1-x/1+x., then find f inverse (x)​

Answer 1

Answer:

x+1/-x+1

Step-by-step explanation:

f(x)=-x+1/-x+1

inverse of f(x) is f(1/x)

= x+1/-x+1

Answer 2

Answer:

f⁻¹[x]=1-x/1+x

Step-by-step explanation:

letf[x]=y say

      x=F⁻¹[y]

    y=1-x/1+x

    y+xy=1-y  

   x[y+1]=1-y                                                                                                                                                            

   x=1-y/y+1

  x=1-y/1+y

∴f⁻¹[x]=1-x/1+x
