find f1(x)

1. f(x) = (x^3 -2x+1)^4
2. f(x) = x^2 (x + 1)^-1
3. f(x) = (x^2 - 4) ^-1/2
4. f(x) = x+1 / x^2 - 4
5. f(x) = (x+1 / x-1)
6. f(x) = x sqrt(1-x^3)

Hey everyone. I'm trying to select a class for my next term and wondering which class I should take between the two. I'm very logical and I love algebra as well as geometry. I've asked my professors what class I should take, and so far I've gotten mixed answers. I know that if I wanted to take some time off from algebra, I would head off into Trig; however, if I want to stay on with some more advance algebra, I'll pick Pre-Cal. I have had experience with both classes inside high school, yet I'm still having a tough time trying to pick which one to take. Greatly appreciated!

To start with, without using math jargon, what is an asymptote?

Find the vertical, horizontal and oblique asymptote, IF ANY, of each rational function below.

(1) R(x) = (3x + 5)/(x - 6)

(2) F(x) = (-2x^2 + 1)/(2x^3 + 4x^2)

What is the difference between a vertical, horizontal and oblique asymptote, in simple words?

I seriously hate cockroaches, they are the most disgusting, gross, creatures to ever set foot on Earth. I'm sure many of you people out there hate cockroaches with a passion as much as I do, yet, they have survived for millions of years since first evolving in the Carboniferous period. Don't any of you people wish that they died along in the Permian mass extinction which killed about 90 percet of all species on Earth?, or died along with the Dinosaurs?, I just hate cockroaches with such a passion, thats why I have bought Raid recently. Man, are cockroaches really that tought to exterminate?, man, it's like the Devil created them.

thank you for your time please approach this with a open mind, nothing is impossible only highly improbable.

Is D.M.T linked to death,

dmt- hallucinogenic drug

produced in the human brain, is involved in certain psychological and neurological states. As DMT is naturally produced in small amounts in the brains and other tissues of humans, and other mammals,[10] some believe it plays a role in promoting the visual effects of natural dreaming , and also near-death experiences. it is released into the blood stream up death, our brain is alive for 10 to 15 minutes upon death. is it linked to death?

is this a possible answer to a great question?

would it scare you?

I am doing some tutoring and want to check that I am correct when I say: Ionic bonding only happens in salts.That this is always between a metal ion and a non-metal ion, and that ionic structures are always 'giant' (and therefore crystals)? Does ionic bonding happen in simple molecules and what are examples of this if so? Thanks!

Could some please name a few chemical solutions (ie: carbonate, bromide, hydroxide) which change over time. As in, their chemical compositions change so if they were to be used in a reactions lab, they would produce different reactions then if a new solution had been used.
