Yes, the TI-84 is allowed during the ACT.
You can't actually graph it on a ti-84 calculator, but an app on the calculator can. The app is called "Inequality Graphing". Most ti-84 calculators come with that app, but to check go into your apps section on your calculators and find an app called "Inequalz" (short for Inequality Graphing). If you don't have it don't panic; I am sure you will be able to download it form online to your calc. After you open up the app it will look just like the "Y=" button on the calc. just with a "X=" on the top left corner. So click the "X=" and now you can graph X on the calculator.
Click on "Y=" to begin graphing. In the upper left hand corner, there should be a tab that says "X=". Click the up arrow to move the cursor there. Click enter and you should be able to graph it from there! To see the graph, click on "graph". I hope this helps!

The TI-84 is a graphing calculater. It is mostly just an update to the TI-83 calculater.

Unfourtunately, it is not possible to expand with the TI-84. Only the TI-89 can expand polynomials.
Sorry, but no, to my knowledge there are no shells for the TI-84=CSE, and there probably will never be, the last descusions about being in 2006, and the TI-84+CSE is not compatible with the old TI-84 or even TI-84+SE programs. I am sorry to say but you will never have complicated games for this edition of the TI calculators but there are some simple games that don't need shells, such as tetris, worms etc:
You can play Ti-84 games with the 84 keypad but I have yet to find games for the n-Spire CAS. So just download TI-84 games and use the 84 keypad.
Assuming you're talking about the Texas Instruments series of calculators - it has a USB connector - you just need the relevant cable.

Xmin is the lower limit to the graph that will be displayed. For example, if you graph something and set Xmin to 0, then the bottom of the graph will be where y = 0 (0 being the lowest x value o the graph). (The default for Xmin is -10, where the bottom of the graph is at the line y = -10.)
The TI-85 was the second graphing calculator made by Texas Instruments. (The first was the TI-81). The TI-84 is a much newer version and has more functionality and memory. The only real advantage that the TI-85 has over the TI-84 is that it costs less. As far as where you are allowed to use the calculator, almost every test or class that allows a TI-85 will allow a TI-84 as well. The TI-84 is a much better investment. (If the TI-84 is too expensive, look into getting a TI-83. This model is also newer than the TI-85.)
