The change in water vapor in a cloud is modeled by a polynomial function, C(x). Describe how to find the x-intercepts of C(x) and how to construct a rough graph of C(x) so that the meteorologist can predict when there will be no change in the water vapor. You may create a sample polynomial to be used in your explanations.

The x-intercepts are the zeros/solutions of the function. :) You can find the zeros of a polynomial function in many ways: using the quadratic formula, factoring, completing the square...And here is a link that talks about graphing a polynomial: http://www.purplemath.com/modules/polyends.htm Maybe it'd be good to make up a function as an example to work with when answering the question. Teachers seem to like that. ^.^
This web-site will teach me thenb?
Yeah, the site explains how you can determine the end behavior and direction of the function. That way you'll know how to make a rough sketch. It's the same thing I had in my notes when I took this same test. :P I got all points on this question, Lol.
Thanks a lot, this will hopefully help.
No problem. :)
