<p>^ but was that what the question was asking for?</p>
<p>does anyone remember the letter of the answer for the plane m, 6 inches thingy? or whether the answer was the biggest one or second biggest or something like that? bc i dont remember my exact answer…</p>
<p>one of the true choices for the f(x) and f(x+2) was the range is the same. because if you imagine, we just put in (x+2) for all the x values which only affects the graph horizontally so since the two graphs are still opening upwards, then the vertex will be the same except for the x values, therefore the range will be the same (y values dont change)</p>
<p>Not sure if this was discussed already, but does anyone remember the question where it was like y = f(x), line of symmetry is x=3, f(-1) = -1, what is f(7)? Was the answer -1??</p>
<p>Ya it’s -1 all you have to do is reflect (-1,-1) over the line x=3 and u get (7,-1)</p>
<p>who wants to show all the answers within this thread!!???</p>
<p>That reflect one wasn’t nearly as complicated as I was making it out to be in my head. I thought it was too easy, but also that CB was tricking me so I skipped it. </p>
<p>I’m surprised some of you are considering cancelling your scores; it can’t be that bad, right? I’d feel terrible if I did since I’m on fee waivers…</p>
<p>I NEED A 800</p>
<p>I am at 4 wrong right now</p>

<li><p>f(x) = x^4-4x+1, f(x+2)
II and III, cross at one point, have the same range</p></li>
</ol>
<p>Ah, crap. Currently at: missed 2, skipped 4.</p>
<p>oh cant forget that interest one. when it has to equal 6 mil</p>
<p>so 6E6=5.7E6(1+.o15)^t solve for t so log base 1.015 of (6E6/5.7E6) equals the minimum t could be and it was a fraction and asked for whole number so you go next number up cant remember what the answer was though</p>
<p>^ I believe the answer was 4 years?</p>
<p>yeah i think answer was like 3.349 and next number up was 4 so yeah. you did it the way i did?</p>
<p>I can never remember that formula 
So I just took the original number, added 1.5% of it, took the result and added 1.5% of that… I did that 4 times until I got a number larger than 6 million, so it was 4 years.</p>
<p>haha for future references P(x)=P(1+r/n)^nt</p>
<p>I did the same as Neytiri. :] It worked nicely.</p>
<p>what number on the test was the one with symetry at x=3 and find the other point?</p>
<p>Could any of you experts be so kind as to tell me the final scaled score of the following (assume a harsher scale if unsure)?</p>
<p>Omitted: 0
Incorrect: 5
Raw: 45 - (5/4) = 43.75</p>
<p>Omitted: 0
Incorrect: 7
Raw: 47 - (7/4) = 41.25</p>
<p>Omitted: 0
Incorrect: 9
Raw: 41 - (9/4) = 38.75</p>
<p>When doing practice tests I used the hardest scale possible, which set 46 RAW as the minimum for an 800.</p>

<p>That problem is #10. See [url="<a href="http://talk.collegeconfidential.com/1064774849-post389.html"]here[/url">http://talk.collegeconfidential.com/1064774849-post389.html"]here[/url</a>].</p>
<p>I would say 800, 780, and 760.</p>
<p>Wait. Wasn’t the question the absolute value of x not the greatest integer in x (see 15 on charizarrd’s consolidated list of answers pg 26)?</p>
