Assume \(A\subseteq C\) and \(B\subseteq C\), we want to show that \(A\cup B \subseteq C\). To prove that the intersection U V is a subspace of R n, we check the following subspace criteria: The zero vector 0 of R n is in U V. For all x, y U V, the sum x + y U V. For all x U V and r R, we have r x U V. As U and V are subspaces of R n, the zero vector 0 is in both U and V. Hence the . The following diagram shows the intersection of sets using a Venn diagram. As a freebie you get $A \subseteq A\cup \emptyset$, so all you have to do is show $A \cup \emptyset \subseteq A$. Consequently, saying \(x\notin[5,7\,]\) is the same as saying \(x\in(-\infty,5) \cup(7,\infty)\), or equivalently, \(x\in \mathbb{R}-[5,7\,]\).
