When I graph two graphs and then find the intersects the coordinates of the intersects are always rounded up. like, the x value for one of the coordinates was 2.15 but it gave me 2.2 but i needed to see 2.15. how can i get it to leave about 4 numbers behind the decimal?I tried messing with the floats for graph and geometry... doesnt work. I've got a finals pretty soon please help.

This is probably because you have the stat plot on. You would need to go to y= and then go to the top where it says stat plot 1 and un highlight it if it is highligted. That should fix your problem.

You have either entered data in lists where one list is longer than the other or in your y= screen, one of the plots is turned on. If a plot is turned on the letters are in white surrounded by a black box. To turn off the plots, higlight the plot that is on and press enter.
Another fast solution is to press, 2nd the the plus sign then the numbers 7 then 1 then 2. It will restore factory settings.

From a lack of a response I'm assuming this is no longer a problem. If it is still a problem, please post a comment specifying the error message.

I believe I already showed you with a profusion of details how to graph functions on the calculator. It would very kind of you to refer to the post that answered your question, so as not to make us answer it all over again. Much appreciated.
Read the following to use the intersection function.
Here are some screen captures
Testimonial: "Thank you so much for answering this and my previous one, it is really very kind of you.I am sorry for being so stupid with the calculator. I can work this out manually but can never manage to get the right information on the calculator despite using a book called Tapping in Mathematics. Thanks to your very clear explaination, it seems so easy now. "
