Re: HELP ME
Vonne, WHY are YOU looking at ANY of this ?
did I miss something abelian or lie get released from tptb in spoilers ?
where is this math urge coming from ?

Re: HELP ME
It is not by choice, yung. For some insane reason, someone in the Liberal Arts field has to do two math classes. I have no idea why. I think it's some type of sick joke.

Okay, here's what my textbook says about the Intermediate Value Theorem:
"Let a and b be real numbers such that a < b. If f is a polynomial function such that f(a) =/= f(b), then, in the interval [a,b], f takes on every value between f(a) and f(b)."
Right. So I'm looking at the examples and it's like oh, I kind of get that. They're saying that if, in a function, you have the points (1, 1) and (2, 5), that means that there is a zero or xintercept between 1 and 2. Right?
So I start finding points in the function I list above. Here are the points I get: (2, 19), (1,1), (0, 3) (1, 7)
So I'm figuring, oh, great! This means that there is an xintercept between 1 and 0.
But no! I go to graph it on my little graphing calculator, and I get this insano graph. The xintercept is between 2 and 3. Now, I was right about (1, 7). I was right about (0, 3). But where I should have the point (1, 1), instead I have like, (1, 30). What in the hell is going on? Can anyone explain this to me?

can you repeat that in english?

My degree is in liberal arts and all I had to take was plain old algebra/geometry crap...math 101. I don't even know what math that is that you're trying to do. I have to say I'm impressed with the smarties around here...TBC and ILF (would he be FreckTheFirst????)

I mean, I'm right in thinking that if a negative is taken to an odd exponent, it stays negative, if it's taken to an even exponent, it becomes positive?
So I still don't really understand where I'm going wrong with this, but it's nice to know that someone else gets it and I'm not going completely insane.
So thanks. You rock.

Yes, a negative number would be a positive number if taken to an even exponent and a negative number if taken to an odd exponent. My bet? Something went goofy when you calculated the value for X=1. Just a guess, but was beer involved?
If you messed up the signs on all of the terms after x^4, you'd get 3  9 + 5 + 4 + 1 + 3, which is equal to 1.
BTW, it always seemed like cruel and unusual punishment to make a liberal arts major do algebra.
