Question

find inf(H), where H={yeQ: y is an upper bound on {xeR:e<=x 11 years ago

Answer 1

\[H=[y \epsilon \mathbb{Q} : y ,is ,an ,upper, bound ,on ,[x \epsilon \mathbb{R}:e \le x <\pi]]\]

Answer 2

the way I see it is that no because if it's y and y is an upper bound then how can it have a minimum?

Answer 3

orrrr is it that the inf of H is actually the sup of the last set
