Topic: How can I add the graph of X=1?
Hello,
I manage to create the graph of the function F(x)=3x^2 very easy but I can't find how to add the graphs of X=1 and X=2 as well.

From the FAQ at http://www.padowan.dk/faq/:
Q: How do I plot a vertical line?
A: A vertical line can be drawn as a parametric function. Select Parametric function as Function type when adding the function. You can then add the vertical line at x=5 as x(t)=5, y(t)=t. Alternatively you can add x=5 as a relation.
