How to use this calculator
Enter a supported function of x, add it to the graph and choose an increasing x range. Compare curves by toggling their visibility and reviewing the axis scale.
How to use the result
The graph evaluates expressions at regularly spaced sample points across the selected range. This is a numerical plot, not a symbolic proof of a function’s behavior between those points.
Functions with undefined or nonfinite values can have gaps. Examine the formula and domain before interpreting a line near a discontinuity.
Assumptions and limits
Sampling is bounded to 1–2000 subdivisions. A sampled curve can miss a narrow feature or suggest a connection across an asymptote. The active function-entry flow adds Cartesian expressions; do not assume it offers a complete polar or parametric plotting tool.
Worked example
For x^2, values at x = -2, 0 and 2 are 4, 0 and 4. The curve is symmetric about the vertical axis and has its minimum at the origin.
