FROM QUESTION TO GRAPH
Start with a little curiosity.
You don’t need to know every key.
Start with one function and take it from there.
YOUR FIRST GRAPHy = x² − 4
A parabola with a lowest point at (0, −4) and x-intercepts at −2 and 2.
Open calculator- 01
Give it a function.
Open y=, select Y₁ and press clear. Enter X,T,θ,n x² – 4. Clear other Y= entries for this example.
- 02
Set the scene.
Press zoom, then 6 for ZStandard. This sets the viewing window from −10 to 10 on both axes and draws the graph.
- 03
Follow the curve.
Use trace and the arrow keys to explore. The curve opens upward and crosses the x-axis on either side of the origin.

A FEW THINGS TO KNOW
Before you dive in.
How it works, what gets saved,
and what to expect.
Is the online calculator free?
Yes. You can open TIHub and use the calculator without an account or a software installation. Your browser downloads the calculator files the first time you open it.
Where does my saved session go?
Save session stores one calculator state in this browser on this device. Return to the same site and browser, then choose Restore session. It does not sync to the cloud or to other devices. Clearing your site data removes the saved session.
Can I import my own TI programs?
You can import supported TI program, group and variable files (.8xp, .8xg and .8xv). Compatibility depends on the file, calculator model and required libraries. Extract ZIP downloads before importing. A file extension alone does not guarantee that a program will run.
Can I use it on my phone?
Use the on-screen keys in a current browser that supports WebAssembly. On a small screen, the keyboard stacks vertically and the save and import controls appear below it. Performance and browser storage availability can vary by device.
Is TIHub an official Texas Instruments product?
No. TIHub is an independent project and is not affiliated with, sponsored by or endorsed by Texas Instruments. TI-84 is a trademark of Texas Instruments.
