Question

What it's a finite interval?

Answer 1

I think it means length is finite, but its a weird way of saying it...I dont get much on google.

Answer 2

i think so, the bounds are some numbers other than infinity
(-infty, 2) is not a finite interval maybe

Answer 3

must be

Answer 4

are all intervals infinite ?

Answer 5

all non degenerate

Answer 6

just a dumb basic q, (1, 2) is infinite right ?

Answer 7

oh degenerate means ?

Answer 8

degenerate means only one element [a], (a,b) is infinite by density of reals

Answer 9

yes (1,2) is infinite

Answer 10

like, (1, 1) ?

Answer 11

that is empty, because 1 is not included

Answer 12

or [1, 1] i think...

Answer 13
