Topic: How do i plot this function..?

i am unable to plot x=constant parallel to y axis..plz help me on this.

one trick is to insert f(x)=constant and then draw normal to it at specified x and then hide f(x)..

But this is not the proper way to be done...any suggestion

From the 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.
