Plot of a real Function

Line Style



Range of the axis
x-min= x-max=
y-min= y-max=
Range of the parameter
a-min= a-max=
b-min= b-max=
c-min= c-max=
Actual value of the parameter


The input of the function must be in the notation of the JavaScript syntax.


There are three constants a, b and c are available, which can be changed using the slider. In the Function to the values ​​specified by the a.Value (), b.Value () or c.Value () is accessed.

Grafical plots

f(x) =

In the function plot the parameter can be changed by moving the sliders.
