Help with intervals plz?
I know how to do like [2,3] and (2,3),
but how do you [2,3]' and (2,3)'?
your notation is unfamiliar to me.
please post the problem in its entirety
you may mean the compliment, in which case $\displaystyle [2,3]' = (-\infty,2) \cup (3,\infty)$ and $\displaystyle (2,3)' = (-\infty, 2] \cup [3,\infty)$, but i am not sure that's what you're after
