Is this a true statement: Suppose such integer k exists. I have proved this. However, I am trying to state it in a "proof" style way. The statement: k is an element of real numbers and has a domain of (-inf, 0)U(0, inf). Notice: I'm not asking you if k actually exists or for you to find it's domain. I'm asking if the statement I made is actually correct.

OpenStudy (anonymous):

Sorry, delete that "is this a true statement" at the top. It doesn't make sense

OpenStudy (anonymous):

What do you mean by domain, it isn't a function...

OpenStudy (anonymous):

\[ k\in \mathbb{R}\wedge k\neq 0 \]

OpenStudy (anonymous):

ok I see what you are saying...

OpenStudy (anonymous):

See, good thing I asked this.

OpenStudy (anonymous):

that makes much more sense. k is an element of the real numbers and k cannot equal zero. This is what you stated, correct?

OpenStudy (anonymous):

Yes.
