What is the inverse of f(x) = x/x-1 ?
this is my attempt to solve it:
y = x / x-1
y(x-1) = x
hence x(x-1) is the inverse.....
however, substituting with x=5 gives......
so pluging this is the inverse function should give 5, right?
1.25(1.25-1) = 1.25*.25= 0.3125. WRONG!!
can anyone tell me where I went wrong?
