<p>Don’t worry, I feel your pain.
Not only is our Stat teacher bad, our book is 17 years old :]</p>
<p>Also, limits should be easily learned.</p>
<p>In a typical function, plug whatever X is reaching.
In a rational function, factor first.</p>
<p>If the limit reaches a # when X approaches infinity, there is a horizontal asymptote
If the limit reaches infinity when X approaches a #, there is a vertical asymptote.</p>
<p>When you are drawing the function from limits, just draw the ends. :]</p>
<p>That’s a crash course on limits. lol</p>
