Is this a full graphing calculator?
It produces a table of values for sketching—not an interactive canvas.
Graphing Calculator
Generate a table of (x,y) values for a linear or quadratic function—educational table, not a canvas plot.
Function and x-range
Choose the function, coefficients, and xmin → xmax with a step size.
About this calculator
How to use Graphing Calculator, plus the formulas and logic behind the results.
Tool description
A table of values lists inputs and outputs so you can sketch a graph by hand. This tool evaluates the polynomial on a uniform grid.
How to use
- Select linear or quadratic.
- Enter coefficients.
- Set xmin, xmax, and a positive step.
- Select Calculate to view the (x, y) table.
Formulas & reference
y = ax² + bx + cy = ax + bx runs xmin, xmin+step, … while x ≤ xmax
Limits
- Maximum 101 rows per run
- Step must be > 0
- xmin should be ≤ xmax
- Use smaller steps for finer tables
Calculation logic
Walks x from xmin to xmax by step (max 101 rows), evaluates y, and joins pairs into a compact table string.
Not a visual canvas grapher—output is a numeric table for learning and plotting by hand.
Graphing Calculator FAQ
Common questions about this calculator and how to use the results.
Why is there a row limit?
To keep results readable in the page layout.
Can step be a fraction?
Yes, e.g. 0.5.
What if xmin > xmax?
The calculator reports an error.
Does it plot asymptotes?
No—only polynomial evaluations on the grid.
How do I graph from the table?
Plot each (x,y) pair on graph paper and connect smoothly.
