This program is a tool to quickly graph a relatively complex function. It teaches principles such as variable substitution and function composition by encouraging the user to experiment with variables and look at random functions.
f  a function composed of two other functions, g and h. 
x  is the variable on which both g and h depend. 
a and b  two constants for g and h, respectively. 
xmin, xmax, etc.  determine the boundaries of the graph window. 
point size  determines the size of the red dots on the graph. 
point density  determines the distance between the red dots. 
autofit y  allows the program to automatically calculate ymin and ymax. 


Redraw  refreshes the picture 
Random Change  changes one of the variables. 
Reset All Variables  returns the variables to their original values
