Home › Graphing Calculator
Free online graphing calculator. Plot mathematical functions, equations, and visualize graphs interactively.
The graphing calculator plots equations and functions visually, so you can see their shape, intersections, asymptotes, and key features. It supports multiple equations on one set of axes with zoom and pan controls.
Students from algebra through calculus, math teachers preparing visual examples, and anyone exploring how a formula behaves before working with it analytically. Engineers and scientists use them to verify expected curve shapes.
It turns abstract equations into pictures, which makes it easier to find roots, maxima, minima, and intersections. It also helps confirm — or correct — answers obtained algebraically.
It answers questions like "Where do y = x² − 4 and y = 2x cross?", "What is the shape of y = sin(2x) over [0, 2π]?", and "Does this rational function have a vertical asymptote at x = 3?"
