Hi All,
Just wondering whether anyone can help?
My Casio Classpad 330 is having difficulty graphing. It is tempermental and will easily graph x^2+3x but when I try to graph -x^2+92x-720 it comes up with a linear graph of something like x+5.
Graphing things like cubics and quartics aren't working either...
I've pressed the reset button on the back numerous times but it doesn't change anthing.
Everything else on the calculator seems fine. It's just the graphing part.
Any suggestions?
Thank you!

Hello Whakama and welcome to UCF! You should introduce yourself.
Have you tried doing a software reset? The reset button on the back only reboots the OS... I don't actually own a Classpad, but on the fx9860/PRIZM you can do a software reset by going into settings, don't know if that helps.

check the function
http://www.wolframal...t(-x^2+92x-720)
it seems the problem is range of this function (e.g. f(0) = -720). According to me, you see only the part of mentioned function which can be interpreted as "linear" in displayed range.
