Boundry points of a set

[alex423]

A = {(x,y) ∈R2 : y^2 < x < 1}

What are the boundry points of this set? Does y^2 = x and 0≤x≤1 cover it?

That sounds like you have the right idea, but you'll need to define this set more precisely. You don't mean every point where y^2 = x together with every point where 0≤x≤1, right? Nor (I hope) do you mean the intersection of those sets.

Try again to say exactly what you mean.

It will also be helpful if you tell us the context of the question. What topic are you studying, and is this the exact wording of a problem given to you?
