Introduktion

Graphing Calculator — Plot points for linear or quadratic functions. Enter Type, a, b, c, X min, X max, Step to get an instant, accurate result.

Formel

Computes y-values across a range of x, using y = mx+b for a linear function or y = ax²+bx+c for a quadratic function, stepping from the minimum to maximum x by the chosen step size.

Eksempel fra virkeligheden

Example: With Type = linear, a = 2, b = 1, c = 0, X min = 0, X max = 2, Step = 1, the Graphing Calculator gives Points: 0, 1, 1, 3, 2, 5.

Ofte Stillede Spørgsmål

Which function types are supported?
Linear (y = mx+b) and quadratic (y = ax²+bx+c).
What does the step size control?
How finely spaced the plotted x-values are — a smaller step gives a smoother curve with more points.
What inputs does the Graphing Calculator need?
You'll need to provide: Type, a, b, c, X min, X max, Step. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Graphing Calculator?
The Graphing Calculator applies the formula exactly as calculated — Computes y-values across a range of x, using y = mx+b for a linear function or y = ax²+bx+c for a quadratic function, stepping from the minimum to maximum x by the chosen step size. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Graphing Calculator free to use?
Yes, the Graphing Calculator is completely free, requires no signup, and runs instantly in your browser.

Om Grafisk lommeregner

The Graphing Calculator uses a real, verifiable formula — Computes y-values across a range of x, using y = mx+b for a linear function or y = ax²+bx+c for a quadratic function, stepping from the minimum to maximum x by the chosen step size. — so results are accurate every time, not an approximation.
