Graphing Polynomial Functions – Free Calculator Tool

This tool will help you graph polynomial functions easily on your website.









Graphing Polynomial Function Calculator

This calculator allows you to graph polynomial functions of the form 2*x^3 – 4*x^2 + x – 5. Input your polynomial, specify your desired range for the x-axis, and define your step size. Click “Calculate” to generate the graph.

How to Use

  1. Enter the polynomial equation in standard format with coefficients and powers (e.g., 2*x^3 – 4*x^2 + x – 5).
  2. Specify the start and end values for the x-axis range.
  3. Enter the step size for how precise you’d like the calculation to be.
  4. Press “Calculate” to generate the graph based on the input parameters.

How It Works

The calculator parses the polynomial equation and evaluates the function over the specified range with the given step size. It then maps these points to the canvas for visualization.

Limitations

This calculator directly interprets the polynomial string and may not handle syntax errors gracefully. Ensure the polynomial is in appropriate mathematical format. Also, very large ranges or very small step sizes may result in performance issues.
