FOOPLOT

Fooplot is a program for drawing functions. There are also similar programs like Graph Sketch.
You can sketch the function for online  in 3D or 2D with root and intersection finding, easy scrolling, and exporting features


You will draw on the picture below to place're writing function.

For example I write it x^2 and I change its setting like that

 

You can fix the border of x-y plane

For example, My graphs' borders are -6 and 6 on the place

-4 and 4 on the y plane.

I changed its window on the x-y plane. Finally I obtained this graph.

We can do some change on our graph.

 We can change background color

and We can also add or drop "grid", "axes", "tick marks"," number"

There is also logarithmic function which is based on

log(x-2)

Let sketch these functions

x^4

This function x^2(x-2)(x+2)
 Hyperbolic Trigonometric Functions, Absolute Value, Ceil(x) can be writing in this program and You also  create polar, parametric and points.
