Question

Please Help!!!!!!

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.
f(x) = x-7/x+3 and g(x) = -3x-7/x-1

Answer 1

Oh gees. Didn't we do this problem a few days ago?

Answer 2

...no i dont think so

Answer 3

Take the function f and replace every x with the function g. Then simplify and you should get x.

Answer 4

Then take the function g and replace every x with the function f. Then simplify and you should get x.

Answer 5

That shows that they are inverse functions because the f(g(x))=g(f(x))=x

Answer 6

ohhh okay I get it thank you so much!!
