<p>So I really need some help with limits because I have a test tomorrow. </p>

<ol>
<li>Lim (as x approaces 11) l 11 -x l / 11-x</li>
</ol>

<p>I got Does not Exist</p>

<ol>
<li>Lim (as x approaches 0) x^3 +12x^2 -5x / 5x</li>
</ol>

<p>I got 0</p>

<ol>
<li>lim (As x approaches 0) ((1/x+8) - (1-8)) / x</li>
</ol>

<p>I got Does not Exist (Is it 0?)</p>

<ol>
<li>Lim (as x approaches 0+) 7x/ l x l</li>
</ol>

<p>I have NO clue</p>

<ol>
<li>Let lim (as x approaches 7) f(x) = 10</li>
</ol>

<p>Let lim (as x approaches 7) g(x) = 9</p>

<p>What is f(x) - g(x) as x approaches 7</p>

<p>Is teh answer 1?</p>

<ol>
<li>Let lim (as x approaches -5) f(x) = 2 and lim (as x approaches -5) g(x) = -3 </li>
</ol>

<p>Find f(x)/g(x)</p>

<p>is the answer -2/3</p>

<p>[lim</a> 7x / abs(x) as x approaches 0+ - Wolfram|Alpha](<a href=“lim 7x / abs(x) as x approaches 0+]lim - Wolfram|Alpha”>lim 7x / abs(x) as x approaches 0+ - Wolfram|Alpha)</p>

<p>Change the formula to the others you need to see the answers for. It’s useful for checking yourself.</p>

<p>Plug them into a TI-89 to check yourself.</p>
