What Is a Graphing Calculator?
A graphing calculator is an online mathematical tool that converts functions and equations into visual graphs. Instead of evaluating an equation only one value at a time, you can see how a function behaves across a selected range of x and y values.
This free graphing calculator lets you plot functions online, compare multiple equations, change the graph range, show or hide grid lines and axes, and explore the coordinate plane using zoom and pan controls.
It can be useful for students, teachers, developers, engineers, and anyone who wants to visualize mathematical relationships directly in a browser.

Frequently Asked Questions
What can I graph?
You can graph functions written using x, including polynomial, trigonometric, logarithmic, exponential, square-root, and absolute-value functions.
Can I graph multiple equations?
Yes. You can add up to six equations and display them together on the same coordinate plane.
How do I zoom the graph?
Use the Zoom buttons or scroll your mouse wheel over the graph. You can also drag the graph to pan around.
What does x^2 mean?
The expression x^2 means x squared. For example, if x is 3, x^2 is 9.
Are trigonometric functions supported?
Yes. Common functions such as sin(x), cos(x), tan(x), asin(x), acos(x), and atan(x) are supported. Trigonometric functions use radians.
Can I use this graphing calculator on mobile?
Yes. The calculator layout is responsive and can be used on phones, tablets, laptops, and desktop screens.
What is the difference between a graphing calculator and a regular calculator?
A regular calculator focuses mainly on numerical calculations, while a graphing calculator lets you visualize mathematical functions and equations.
Important Note
Graphs are numerical visualizations generated from the entered function and selected viewing range. Very large values, discontinuities, or rapidly changing functions may appear differently depending on the selected graph range and sampling resolution.
