 travisslack determining the x-intercept. set the numerator to zero, or the denominator? HiLander maybe. thermoplyae Is 0/x 0?Is x/0 0? HiLander what does this have to do with an x-intercept?that's the question i want answered kilimanjaro x intercept usually means the set intersection of the image of a function with the x axis travisslack as in... (x^2 +1) / (2x^2 - 3)do you set the bottom or top to find x-intercept kilimanjaro travisslack, the x-intercept is the x such that f(x) = 0 godling travisslack: if the bottom is zero, that means the function would be undefined. think of it like setting the entire thing equal to zero, then multiply each side by the denominator. kilimanjaro That rational function has no real zeros, but it does have a complex zero thermoplyae Like I said, is 0/x 0 or is x/0 0?That is not really an opaque hint merus he's gone. thermoplyae whoops kilimanjaro merus, chalk another death up to divide-by-zero error merus ayup godling looks like we need another timmy action merus wants to take everyone back to the good old days when group theory was about permutations and solving quintic equations with radicals might be possible merus wants to take everyone back to the good old days when group theory was about permutations and solving quintic equations with radicals might be possible HiLander yeah, i miss the days of tuberculosis too kilimanjaro merus, permutation? Is that some sort of manifold?! merus HiLander, you mean consumption? TRWBW merus: don't forget the constructions. aaah, the smell of the ruler, the taste of the compass... merus My new time-machine plot (after the assassination list) is to go back to the 1870s and teach Sylow the class equation so he wouldn't have to fool around with rational functions in several variables. HiLander actually, my plan is to go back in time to punch HG Wells in the facei've already edited wikipedia several times to indicate its occurrencebut somehow, people can't believe it. buggler hehe matt5 lol kilimanjaro HiLander, ignore those people. They only want to bring you down. Move onward, time cowboy. matt5 Time travel is impossible, because then the earth's rotation and the whole universe would have to retrace/go reverse... buggler thanks for clearing that up matt5your argument was quite compelling matt5 ... what's that suppose to mean? merus Help! What if I were trapped in a hypothetical situation? matt5 don't hate; appreciate godling isn't that what happened when superman did it? kilimanjaro matt5, yes, the entire universe would retrace, but in the future. So it's no surprise that it hasn't happened yet. HiLander i'm not even kidding: http://en.wikipedia.org/w/index.php?title=H._G._Wells&diff=125418025&oldid=125405251
