How do you find the inverese function of f(x)=x/(x+1). Inverse means replacing x and y not reciprocal. I already know the answer (by pure luck) but I don't know how to figure it out. Please help me!

There has been quite a bit in the news recently about finding "New Earths." I am looking for some journal articles that contain the following information:
1. Methods of finding Earth-like planets
2. Characteristics of Earth-like planets
3. Documented Earth-like planets

I have already seen pretty much everything the web has to offer. I'd like references to science journals or scientists working currently researching Earth-like planets.

If you are an astronomer, I'd value anything you may have to say about Earth-like planets too.

Okay here's the question:

Find and simplify f(a+h) - f(a) (h cannot = 0) for the function.
__________
h

f(x)=x^2-2 (that means f of x equals x squared - 2)

I dont understand what I'm supposed to plug in for a and h. I'm not given what theyre equal to. Please help!
