Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

f(x) = quantity x minus nine divided by quantity x plus five. and g(x) = quantity negative seven x minus eight divided by quantity x minus one.

This is a "confirm".  Just do it.  Construct f(g(x)) and g(f(x)).  Simplify each and see that you get "x" as the simplified result.

I did but I got it wrong so I feel like I made a math error, do you have work with it that I can see to see what I did in my work wrong?

Show your work.  Maybe they are not inverses.  Prove it one way or the other.  Show your work.
