Introduction to FX Graph 5
Getting Started
Click on the y= button (or right click on the graph) to enter a
Each Line is a Function
The function entry section of the Quick Entry screen allows for
multiple lines. Each line will be graphed as a separate function.
Points Of Interest
FX Graph finds points of interest automatically. As you move the
mouse around, FX Graph will show you any points of interest near
the cursor.
Right Click Menus 1
Many features are accessed by right-clicking on the graphs
A. Right-clicking at point A will open the
Quick Entry screen - the one we
have been using to enter our
B. Right-clicking at point B will open the
Scales screen which will allow you
to set the scales you use for the
C. Right-clicking at point C will offer a
right click menu (providing FX Graph
has found the function and displayed
it for you).

Cartesian / Inverse
Cartesian Functions
FX Graph never needs to be "told" what type of graph to
draw - it automatically determines the graph type by
what you type. To draw a Cartesian function, just use x's
– to draw Inverse Cartesian functions, use y’s.
3x2 + 2x - 4
y = 3x2 + 2x - 4
f(x) = 3x2 + 2x - 4
3x2 + 2x - 4 - y = 0
3y - 4/y
x = 2y2 + 3y - 4
f(y) = 3y + 4
Using the Function Entry
System 1
The function has no y = but FX Graph will
interpret it as a Cartesian function anyway.
We have not had to do anything to get FX
Graph to interpret x2 as x squared. Most of
the time, FX Graph will find powers
We have used the / sign to represent division.
We have wrapped the numerator and
denominator of the fraction in brackets - not
too tricky as most mathematicians realize that
the fraction line is a de-facto bracket.
We have used sqrt to represent square roots.
We could have used sr instead.
