Plot and visualize mathematical functions with multiple overlays
Visualize mathematical functions in 2D by plotting equations and exploring their behavior interactively. Enter any combination of polynomials, trig functions, exponentials, or logarithms and watch them render on a dynamic coordinate plane. Overlay multiple functions to compare shapes, find intersections, and spot trends. Interactive zoom, pan, and trace controls let you inspect specific regions with precision.

You need to see where the parabola y = x² − 3 crosses the x-axis without solving it on paper.
Function
y = x^2 - 3
Plot insight
Roots at x ≈ ±1.732 (±√3) Vertex at (0, −3), opens upward
The curve is rendered and key points are readable directly: it dips to its minimum at (0, −3) and crosses zero at ±√3. Plotting multiple functions on shared axes makes intersections and behaviour obvious in a way a table of values does not.

Graph quadratics, cubics, and rational functions to understand roots, vertices, and end behavior.
Plot a function alongside its derivative or integral to see slopes and areas graphically.
Project live graphs during lectures, adjusting parameters in real time to illustrate concepts.
Overlay a proposed model equation against data trends to verify fit before formal regression.
Graphing turns abstract formulas into shapes you can reason about visually. Instead of plugging in dozens of x-values by hand, the plotter samples the function across the viewport and connects the results into a smooth curve. Adaptive sampling increases point density near sharp turns or rapid oscillations so features like cusps and steep slopes render accurately. The tool also detects vertical asymptotes and avoids drawing misleading connecting lines across discontinuities.
Use the caret symbol: x^2 for x squared, x^(1/3) for a cube root, and so on.
You can approximate piecewise behavior by plotting each piece as a separate function and limiting the view window.
