Function Grapher and Calculator

Description :: All Functions

Description

Function Grapher is a full featured Graphing Utility that supports graphing two functions together.

It has the unique feature that you can 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, or choose your own letter, then press the Plot button.

You can use the "Calculate" button to see how your formula has been interpreted.

Zooming and Re-centering

To zoom into an area, select an area with the mouse (click, hold down and drag, then release). The area you selected will be the new bounds. This will result in the x and y scales being different.

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

You can zoom out using the Out 2X or Out 10x button.

To reset the zoom to the original bounds 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.

Note how I used a*x to multiply a and x. If I used ax (or xa) the program just gets confused.

You can change the smallest and largest value of "a" by changing the numbers at the start end end of the slider.
