Enter a function f (x) in the text input field
marked "f (x)="
(Example:f (x) = x^{2})
Click the "Graph" button
(this button also refreshes the graph)
Select values for x_{1} and x_{2}
(Example:x_{1}=0, x_{2}=1)
This can be done in either of two ways:
Use the mouse to click and drag the
red points on the graph --
the points follow the graph of f (x), and the
values of x_{1} and x_{2}
correspond to the horizontal positions of the points on graph
Enter the values in the text input fields marked
"x_{1}=" and
"x_{2}=",
and click the
"Graph" button to refresh
To erase the graph and all input fields (setting
x_{1} and x_{2} to default values), click the
"Clear" button
The text input field marked "f (x)=" can accept
a wide variety of expressions to represent functions.
The text input fields marked
"x_{1}=" and
"x_{2}="
can accept a real number in decimal
notation. The
buttons under the graph
allow various manipulations of
the graph coordinates.
