Example To graph y = Ax
2
– 3 as the value of A changes in the sequence 3, 1,

Use the following V-Window settings.
Xmin = –5, Xmax = 5, Xscale = 1
Ymin = –10, Ymax = 10, Yscale = 2

# The value of only one of the variables in the
expression can change.
# Any of the following cannot be used for the
variable name: X, Y,
r,
θ
, T.
#You cannot assign a variable to the variable
inside the function.
#When Simul Graph is turned on, all of the
graphs for the specified variable values are
drawn simultaneously.
#Overwrite can be used when graphing
rectangular expressions, polar expressions,
parametric functions, X = constant functions,
and inequalities.
