I’m not sure you can, as it doesn’t seem to allow one graph to have 2 points at the same x value, you are plotting F(x) which is basically Y=, is what I concluded.

I hope I am wrong, and there is a way to do it.

You can get a good approximation with something like F1(X)=1E20*(X-1) which will plot a quasi-vertical line at X=1 in the Function app.

One approach along these lines would be to add a continuous step function (like Heaviside, but known to be continuous and with the transition from 0 to 1 made in the gap between adjacent floating-point numbers). Such a function could then be scaled and shifted to produce other sorts of (continuous) steps.
