SOLUTION: I need to find the inverse of f(x)=(1/x+2)-1 so far I have gotten y=-2x-1/x+1 (if that is correct so far, im not sure) my answe key says the answer is f^-1(x)=-(1/-x-1)-2

Question 938600: I need to find the inverse of f(x)=(1/x+2)-1

Not sure what you really have to start with,
you want the inverse of f(x)=(1/x+2)-1 or when rendered, .

Let g(x) be the inverse of f.
---meaning of the inverse of a function
---using g as the input of f
