Grafolyn’s Graphing Calculator Shows the Answer, Not Just the Curve
A browser-based graphing calculator for functions, data, sliders, roots, intersections, regression, and exportable graphs.
- For
- Students, teachers, and people checking equations
- Worth noticing
- Regression covers eight model families and reports when a requested fit cannot support the supplied data.
Field notes
The calculator accepts ordinary equations as well as inequalities, implicit curves, restricted domains, piecewise rules, and standalone points. Its analysis workflow reports roots, local maxima and minima, y-intercepts, and intersections within the visible window, with copy controls for the results. The Data tab accepts points typed into a table or pasted from a spreadsheet, then compares eight named regression families and can decline unsupported fits rather than drawing one anyway.
