Function Grapher and Calculator

Description

Function Grapher is a full featured Graphing Utility that supports graphing up to 5 functions together.

You can also save your work as a URL (website link).

Usage

To plot a function just type it into the function box.

Use "x" as the variable like this:

Examples:

  • sin(x)
  • 2x−3
  • cos(x^2)
  • (x−3)(x+3)

Zooming and Re-centering

To zoom, use the zoom slider. To the left zooms in, to the right zooms out. When you let go of the slider it goes back to the middle so you can zoom more.

You can click-and-drag to move the graph around.

If you just click-and-release (without moving), then the spot you clicked on will be the new center

To reset the zoom to the original click on the Reset button.

Using "a" Values

There is a slider with "a =" on it. You can use "a" in your formula and then use the slider to change the value of "a" to see how it affects the graph.

Examples:

  • x^a
  • 2x−3a
  • sin(ax)
