Example 3. (a) Since $y=\frac{x^{2}+4}{x-3}$ is undefined at $x=3$ : Basically, we say a function is continuous when you can graph it without lifting your pencil from the paper. $\lim _{x \rightarrow-4^{+}} \frac{x^{2}+x-6}{x^{2}+2 x-8}=\lim _{x \rightarrow-4^{+}} \frac{x+3}{x+4}=-\infty .$ Thus, $x=-4$ is a vertical asymptote.
