Manual Graphing

Example

To graph y = Ax2 – 3 as the value of A changes in the sequence 3, 1,

 

–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.
