I NEED HELP!!!!
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.

Best ResponseYou've already chosen the best response.0\[f(x)=\frac{x9}{x+5} , g(x)=\frac{7x8}{x1}\] is this what you mean?

Best ResponseYou've already chosen the best response.0actually, it's possible, it just requires a lot of algebraic simplification to find f(g(x)), take the expression for g(x) and substitute it in for x in f(x), and after simplifying you should get x do the same thing for g(f(x))

Best ResponseYou've already chosen the best response.0Yes I know it is possible to find f(g(x)) and g(f(x)) but the person will not be able to confirm what they wanted @Vocaloid

Best ResponseYou've already chosen the best response.0I think there was a typeo since the question says confirm which means they are indeed inverses but these are not inverses.
