<p>oopsie.. sry it is 25..
u can get abt 8 wrong answers..</p>

<p>If you graph the f(x)=f(-x), one for both functions, then you can tell what the answer is. I believe I got C for the answer.</p>

<p>not 8 wrong answers.....thatd be a 40...
neone have ne idea what cut off for an 800 was the previous years?...</p>

<p>So far I'm 1 wrong and 0 blank. Yay. Don't kill me...</p>

<p>Cutoff was 44 in May 2002.</p>

<p>me too 1 wrong.. but you know.. I am a real stupid person, always making those careless errors</p>

<p>i'm at 49 right, 1 blank woohoo!</p>

<p>lets see: the odd function was wrong, and I forget what I put for lnX^2 and the sin cos product one... so at worst 47 right and 3 wrong, unless I got others wrong...</p>

<p>adding to Psyco Pericles', xyz just means three plains.. it's just indicating there are three plains and how many plains can make up a dot, a ray, and a line. All are possile with three plains, of course. Wasn't math exam pretty easy this time? I was worrying way too much.. I guess.</p>

<p>commenting on what r-akt said: no need to graph all that.. f(x)=f(-x) just means that the graph will be an even function.. meaning when you just graph the lines of 5 choices, one of them will have a shape that can be transformed to a certain spot where the graph can be symmetrical about the y-axis. I don't remember what the answer was.. c or e.. I don't remember though :p</p>

<p>so what was the answer to the question with 3 planes, ray, point, and segment?????</p>

<p>I think that was a point and a line</p>

<p>What was the answer to the one with subtracting the logs and a k? Near the end of the test...</p>

<p>actually, i don't think a ray is possible from the intersection of 3 planes</p>

<p>the one with k log(sub 5) x = f(x)?</p>

<p>that was -k</p>

<p>Really---I was running out of time, so I guessed that. How do you do it?</p>

<p>do you rmbr the full question? I'll explain it</p>

<p>I substituted a random number for "k" and did (log25/log5) - (log5/log5), or something to that extent.</p>

<p>man that was a better way to do it...lol I had to use this long crazy equation...I totally forgot about natural base formula lmao</p>

<p>what was the limit of x^x? I put 0.8...I thought that was right using the graphing calculator. =/</p>

<p>what were the choices and teh exact question</p>
