<p>no i think that piecewise question was something with the point @ x=0 but it was different</p>
<p>yeah, i pulled an edit on you. sorry</p>
<p>I got 2. 10 characters.</p>
<p>yea i got 2 and jigpat sorry i have no idea what questions you’re talking about haha</p>
<p>lol well 2 was the right answer for that one</p>
<p>What about f(f(x)) one? i just said f(x). (This might have been Math 1, I took both and can’t really remember).</p>
<p>If x=acrtany then square root of (1+y^2)=?

<p>nwgolfer- 2 is correct!</p>
<p>RupertPumpkin(interesting username!)- I hink that must have been M1. I don’t recall any such question being in M2.</p>
<p>Protoslg- mod of sec x. (C)</p>
<p>Robert, i remember putting that too!:). Also, for the box and whisper blox 46 was the median and 14 was the interquartile range?</p>
<p>rupert i think there was math 1 </p>
<p>although on II there was one that like like f(g(x)) = h(x) and you had to find h(x), i think i got 2x-2? but im not entirely sure… i think it was f(x) = x+1 and h(x) is 2x-2, does that sound right?</p>
<p>What’s worse than not knowing 1 foot= 12 inch? I didn’t know about it at all. I am an International Candidate studying under the SI system. The foot and inches things are really unfamiliar to me. Somehow, I received a calling that I should divide it by 12. =)</p>
<p>Is it really 11? First, I didn’t know how to do. I randomly chose 12 before time ends. Then, I knew it can never be 12. It just will not make sense since 8+4=12. Somehow, my instinct just doesn’t feel right. So I picked the second largest number. =)</p>
<p>Now I just hope we all get right for some fundamental questions ( like some involving unknowns and graphs.) I seriously need numbers in drawing graphs.</p>
<p>no, it was 2x - 2.</p>
<p>I got 2x-2</p>
<p>what was the answer choice for the one with 2^m = 4^n? i put B, but i forgot which answer that was…</p>
<p>For the one that asked what value Y reaches as x goes to 3/2 was no boundary right?</p>
<p>Oh, and the one about the paper folding was 10 feet?</p>
<p>And, for the one about the phone calls, my friend says it should be 4/9 since the first can be local, second one long dist, or the other way around. so 2/9 x 2… i put 2/9 too :(</p>
<p>I think i got 12 feet for the folding; for the m one, did you have to do elimination to solve for m?</p>
<p>Rupertpumpkin, awesome name. I love entourage!</p>
<p>Btw box and whisker plot?? I didn’t have one.
2x-2 is right pianoman. I just had +, but it’s minus.</p>

<p>If x=acrtany then square root of (1+y^2)=?
A.lsinxl
B.lcosxl
C.lsecxl
Dlcscxl
E.lcotxl</p>
<p>If x=arctany, then y = tanx</p>
<p>Substitute and you have root(1+tan^2(x))=?
We know that 1+tan^2(x)= sec^2(x) because of our identities,</p>
<p>so the square root of (sex^2(x)) = |secx|</p>
<p>the answer to the ones with m and n was 5, i think that was A…there’s an explanation on an earlier page on this thread.</p>
<p>the other two are correct.</p>
<p><em>Speaks up in drony voice</em> 2x-2 is correct. <em>Bams hammer down on desk. Next.</em></p>
<p>PS- Hey everyone, don’t do Math 1 discussion on here. It’ll get confusing for those of us who took only M2.</p>
<p>Protoslg - you’re talking about Math I. The interquartile range refers to (Q3-Q1)<em>1.5, so the range would actually have been (14)</em>1.5 = 21.</p>
<p>Does anyone remember the answer to the one that was like (6n^2)/3n =/= 2n? It asked which one had to be right…</p>
<p>Also, how about the question with the 5 equations, and you had to find out which one had 2 real solutions? The choices were:
A. (x^2+8)(x^2+4)=0
B. (x^3-8)(x^2+5)=0
C. (x^2-1)(x^2+1)=0
and then I don’t remember the rest…</p>
<p>@sirena</p>
<p>I think I put C.</p>
