@@ -17,6 +17,14 @@ The standard notation for a limit is:
 $$ \lim_{x \to a} f(x) = L $$
 - As $x$ approaches $a$, the output of $f(x)$ draws closer to $L$. In the above notation, $x$ and $a$ are not necessarily equal.
 - When plotted, the hole is located at $(a, L)$.

+# Continuity
+A function is continuous if their graph can be traced with a pencil without lifting the pencil from the page.

+Formally, a function $f$ is continuous at a point $a$ if:

+- $\lim{x\rarrow}$
