Function Plotter & Graph Plotter Tool

Visualize mathematical functions with interactive graphs

Function plotter for quick visual checks

This function plotter helps you graph equations in the browser without installing extra software. Type a function of x, adjust the range, and use the interactive function display to inspect shape, intercepts, growth, and discontinuities.

Use it as a graph plot tool for algebra, precalculus, and calculus examples. The built-in plotter functions include common shortcuts such as quadratics, trigonometric functions, square roots, absolute value, exponentials, and logarithms.

How to Use

Supported Functions

  • ^ or ** for power (e.g., x^2)
  • sqrt(x) for square root
  • abs(x) for absolute value
  • sin(x), cos(x), tan(x) trigonometric
  • log(x) natural logarithm
  • exp(x) exponential (e^x)

Examples

  • x^2 - 4*x + 3 quadratic function
  • sin(x) + cos(x) trigonometric
  • 1/x reciprocal function
  • sqrt(abs(x)) combined functions
  • 2^x exponential growth

Graph plotter FAQs

What is the best way to use this plot plotter?

Enter one function at a time, choose an x and y range that includes the important behavior, then click Plot Graph. This plot plotter redraws the chart whenever you adjust the settings.

Which plot tools are included?

The page includes function input, range sliders, grid toggles, smooth curve options, downloadable graphs, and quick examples for common plot tools used in classwork.

Can I use it as a plotter function checker?

Yes. Type a plotter function such as x^2 - 4*x + 3, sin(x), or log(x) to check whether the graph matches your expected behavior.
