Calculator question: solving for Y in TI-83

Can I solve x('s) for a certain value of y using a graphing calculator?

That is, can I plug in y in a function to find the x's?

It seems like that would be a faster way to find the zeros of a function than doing the whole [calc - left bound - right bound - guess] routine.

Thank you.

Can you not tell from the calculator's manual?

We like to talk about cool math programs like your Android app. But please don't spam, you wouldn't like MarkFL when he's angry.

Re: Calculator question: solving for Y in TI-83

It's funny to me, since we're actually happy to have a discussion about these sorts of things -- there's absolutely no reason to spam in the first place!

While we're at it, let me mention something I'd like to see: a version of PARI/GP for the Kindle Fire. If someone would go through the trouble of converting
http://code.google.com/p/paridroid/
for that platform, I'd be happy to shell out a few dollars for it. (Without that, I couldn't use it without rooting my Kindle and doing a bit of conversion, but since the KFire is already running Android it doesn't seem crazy.)
