Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.
f(x) = (x8)/(x+7) g(x) = (7x8)/(x1)
I'm running out of time. I'd appreciate if someone could just help me with this.

Best ResponseYou've already chosen the best response.0dw:1435727045875:dw we're replacing every x in f(x) with g(x) function which gives us f(g(x)) and for g(f(x)) you would replace every x in g(x) with f(x) function, now you can simplify the problem.

Best ResponseYou've already chosen the best response.0@Astrophysics Yea, I can typically get that far, I only have trouble with what comes after that lol. It always gets really messy when I try to attack it, and I always end up getting it wrong somehow.... :(

Best ResponseYou've already chosen the best response.0so, I start off like this? ((7x8)/(x1)8) 7x88x+8 15x

Best ResponseYou've already chosen the best response.0then........ ((7x8)/(x1)+7) 7x8 + 7x7 15 15x/15=x=f(g(x)) I'm assuming it's like this, right? I had an experience where someone overcomplicated it all, but I feel like I'm doing it right....
