Which function is f(x) equal to f^-1(x)?

a. f(x)=x+6/x-6
b. f(x)= x+2/x-2
c. f(x) x+1/x-1
d. f(x) x+5/x-5

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

Step-by-step explanation:

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

Interchange the x and the y

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

Now, we will solve for y

x(y-1) = y+1

xy - x = y+1

y(x-1) = x+1

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

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

f(x) = f^-1(x)

I hope I helped!

Let me know if you need anything else!
