<p>right, I did not think of that. I just solved it like I would any other limit and did not think about the graph. damn.</p>
<p>yeah since if you solve it, the (x+2) cancels with the (x+2) in the denom, so you probably got a feasible answer, but it still doesn't approach a valid number. since if you plug in -2, the denom = 0, and YOU CAN'T DIVIDE BY ZERO.</p>
<p>i think it was something like that. can't remember if it was 1.5 or 2. but yeh</p>
<p>the limit as x -> 1.5 did approach a particular value once the discontinuity was removed.</p>
<p>It was 2x-3 as x approaches 1.5. There was 2x-3 in the numerator and denominator so you just had to cancel it out. The answer was a decimal... I forgot which.</p>
<p>and the log answer was:
lognpr^2 = lognp (5) + 2logn3 (6) = 11</p>
<p>Repentance time...
I am wrong; 99% are right. k<=0.</p>
<p><em>his sock plunged</em>:(</p>
<p>The definition of a limit is that it approaches that number from both sides. It doesn't matter what it is exactly at the point it is approaching. Both sides were approaching a number (I forget what the number was), so there was a limit.</p>
<p>yeah Pengsta it was 1.something I think</p>
<p>what about the one with the sin graph with the A,B,C,D? which one changed to produce the effect? i said it was C? sound right?</p>
<p>What was the answer to the $250,000 4% increase each year problem where it asked how many years until it became worth $2,000,000? I forgot the formula :(</p>
<p>To the guy above, yes it was C.</p>
<p>2x - 3 you say was in the denom? ok so 2x = 3, x = 3/2, x = 1.5
as x approaches 1.5, there is no limit. you see?</p>
<p>if x approaches 1.5 then the equation would be
something</p>
<hr>
<p>(something)(2x - 3)</p>
<p>(2(1.5) - 3) = 0</p>
<p>so then it would be (2x-3)(something) / 0, which means the limit doesn't exist.
if you simplify the equation by canceling out the 2x-3's, then you're not approaching 1.5 in the original equation with the same zeros</p>
<p>was C the thing being multiplied by the degrees?</p>
<p>yeah its C
what about the one ... asked you what the lengeth of BD equals to
the one with a circle and a radius of 1</p>
<p>I remember marking C as well (which was the horizontal shift # if I'm not mistaken), but I don't entirely remember right now</p>
<p>53 years was the answer positive</p>
<p>so what's the conclusion on this limit one?</p>
<p>lostinbalt, that 2x-3 cancels out of the equation with the 2x-3 on the top, leaving another equation where you had a denominator which WAS feasible.</p>
<p>yeah i got 53 too. i think that was E</p>
<p>that one was 53 yeah</p>
<p>I still think you have to keep the equation intact when solving for the limit. I haven't had calculus in a long time, but thats how I always did it, and the people who canceled things out got skewed answers. Can anyone prove this? I don't remember limits, that was such a long time ago.</p>
<p>I put 53 for the age/home thing too.</p>
<p>i remember you have to cancel out the answers for the limit problem</p>
<p>yea, the limits cancel out. you get 6/3.5..? i think if i remember correctly. b/c basically you're saying the lim as x-> 1.5 and then you get 0/0, so you can cancel the 0's out to leave u with a new equation.</p>
