My last question i asked got a very nice response that helped me alot with the other questions like it, for this one Domains and ranges have always eluded me, just something I haven't been able to figure out, this here is a very basic one but i still can't 100% figure it out! On a graphing calc I can see what sqrt(x) is, but how do I figure out the domain and range of that and the inverse of it? Any help would be mucho appreciated!

The full question is:

let f(x) = sqrt(x)
Sketch F and F-1(inverse) on the same coordinate plane
Stage the Df(Domain) and Rf(range)

A rocket is launched vertically and it runs out of fuel at an altitude of 1000 ft. above ground level, when its velocity is 78.4 ft./sec. How long will it be before the rocket again is at an altitude of 1000 ft. above ground level?


Please, please, PLEASE at least give me the equation. Setting up the equation is what I have the most trouble with. :(

Hi, I have two problems to pose. The first one was problem 27
on the 2007 FAMAT( see http://mathgod.com/mathcomps/interschools/fall2007/
and the second one is related to a question recently posed by
(Ω)kaksi _guy.
Anyway, here they are:

1. If n = 4 I get 4 2 3 2 4 3 1 1
If n = 5 I get 3 5 2 3 2 4 5 1 1 4
I don't get anything for n = 6 or 7
What should I get for n = 8?

2. Compute the definite integral
∫(-π/2..π/2) cos 2x dx/(1 + e^(sin(x)).
The limits are -π/2 to π/2.
I ran this through an online program to
evaluate definite integrals and it seems the value of
this integral is 0. Prove it!
