<p>But a 780ish is only like 80th percentile…</p>
<p>see i picked one but my fear is that zero is technically correct. It doesn’t really matter if the question fits the archetype of a different type of question the answer you gave is right</p>
<p>We were still missing a question on the list of all the questions that has been posted. what is that mystery question?! i am at 45 right now, i must know</p>
<p>Are we still unsure of the inverse question? I remember it well. It asked which of the following functions had an inverse. I saw choice A and bubbled it immediately, but I remember that I also saw a graph of f(x) = x^2.</p>
<p>A, which was something along the lines of f(x) = x^3, has an inverse function. Flipping variables and solving for x:</p>
<p>y = x^3 → x = y^3
y = cuberoot(x)</p>
<p>cuberoot(x) has a domain of all real numbers since the cube root of a negative is a negative, and it passes the vertical line test.</p>
<p>Choice B (I think) was something resembling f(x) = x^2. Using the same method:</p>
<p>y = x^2 → x = y^2
y = ±√(x)</p>
<p>This is not a function. It only produces real values for x = [0, ∞) and fails the vertical line test.</p>
<p>The others could all be eliminated by the same method, but if you understand that simple odd power functions have real inverses then that question should be a quick job.</p>
<p>Yeah, that one was pretty simple. Horizontal line test.</p>
<p>has there been a consensus on the parametric one? i’ve been seeing answer D and E thrown around, i remember putting answer D?</p>
<p>Hey guys for 21, r = 6, does anyone remember if it was D or E? I might have derped and chose “4”…</p>
<p>beforethedawn, I think i remember D too. It was whatever had a + sign.</p>
<p>^nuggers thanks! 
also, i think i’m just being overparanoid now, but does anyone remember what answer letter 25 was for the ice cube problem. I remember putting answer D, but now I don’t remember if that was 25 or 26</p>
<p>What was the problem for 28?
The one with the sinx and tan x -.779</p>
<p>@Eddysgotmilk</p>
<p>It was the one where tan theta = something, and it was specified that theta was in the third quadrant, and it asked for sin theta.</p>
<p>Anyone remember the letter choice for the ice cube one? 
Minorly freaking out because that question is the only one I’m not sure about, and it’s the difference between a 43 and a 44 for me
Or alternatively, if anyone remembers about what number the question was, that would be helpful haha (although I’m not sure if anyone has memory that good)</p>
<p>I want to say C? But I’m definitely not sure so don’t hold me to that. I don’t think it was A or E.</p>
<p>I don’t remember if it was C or D :/</p>
<p>Yeah, I was actually thinking C or D as well. I think C.</p>
<p>I remember putting D, but now I’m not sure if that was 26, do you think a 43 could still be an 800?</p>
<p>Honestly, I doubt it. It didn’t really seem hard enough to necessitate a more-than-usual curve. But even if it’s not, there’s certainly nothing wrong with a 790. :)</p>
<p>Isn’t the usual curve a 43 or 44?</p>
<p>Usually, it’s 44, I’m pretty sure. Then about 10 off for every raw point below 44.</p>
<p>Someone please correct me if that’s wrong.</p>
<p>Idk I went off this, [SparkNotes:</a> SAT Subject Test: Math Level 2: Math IIC Scoring](<a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides), but I’ve also heard from other people that 43’s can be 800’s.</p>
