On a suitable set of real numbers, functions f and g are defined by f (x) = 1/x+2 and g (x) = (1/x) - 2
Find f(g(x)) in its simplest form.
I tried this and got x as the answer.
I'm not sure if its right so if anyone can tell me where im going wrong/right it would be great! Thanks.
Sorry for being a compulsive poster but i can't afford to fail at higher maths
