Are x, y, and z elements of the normed linear space ℓ∞(ℝ)?

[I like Serena]

Is it L?

Would you be willing to change that to:

It is L!​

?

(Or else please clarify what is still puzzling you. )

I don't really get "functional analysis"...but I will battle on anyway :-) Thanks

So to go back to what you were trying to figure out much earlier in this thread, the infinity norm of x, where x = {1 - 1/n}, ||x||_∞ = $\lim_{n \to \infty}(1 - 1/n)$ = 1.
