What this tool does
Plot Any Function
Enter y = f(x) in the expression box and the curve draws itself. Implicit multiplication is accepted, so 2x works as well as 2*x.
Layer Several Curves
Add as many expressions as you like to one grid and compare them directly. Each curve gets its own colour.
Table, Zoom & Coordinates
Generate a table of values, zoom in or out, and hover the curve to read exact coordinates at any point.
Step-by-Step Solver
Equations you enter can be worked through step by step — quadratics, linear equations, systems and derivatives, with the reasoning shown.
Frequently Asked Questions
Is this graphing calculator free?
Yes — every feature is free with no account, no trial and no paywall. There is no premium tier hiding the graphing tools.
What can I graph?
Functions y = f(x), polar equations r = f(θ) and parametric equations x(t), y(t). Polar and parametric modes have their own tabs in the toolbar.
Do I need to install anything?
No. It runs entirely in your browser, so it works on a Chromebook, a locked-down school laptop or a phone with no app store access.
Does it show step-by-step solutions?
Yes. The step solver works through quadratics, linear equations, two-variable systems and derivatives, showing each step of the reasoning rather than only a final number.
Is this an official Texas Instruments product?
No. This is an independent, third-party tool. TI-84 Plus™ is a trademark of Texas Instruments Incorporated, which does not endorse or sponsor this site.
