Graphing Software Question

How to I draw the line x=2 in a graph program?
The program (MathGV) only lets you input a function y=f(x) but there is no y variable in the equation of the line x=0?

There's a handy graph utility on Macs called Grapher which is quite powerful and easy to use, although I assume you're on windows.

Is there a reason it has to be x=2?

Essentially y=2 is the same graph, the axes are arbitrarily named.

I want to draw the Vertical Asymptote x=2

Fremen

if you can only plot X against f(x) then unfortunately you can't draw x = 2.

I'm sure you could do it in excel very easily.
Or you could just plot Y = -2 and tilt your head

I assume you yourself know what the line looks like, and therefore that the reason you need to do this is so that you can include this diagram in some document or other intended for other people.

Will you not be pasting the main graph into some other file? And if so, can't you add the asymptote afterwards? e.g. paste into Word and then use the Word drawing tools, or paste into a graphics program and add your line before copying onwards as an image to somewhere else.
