<p>Let's take a poll here...</p>
<p>Vote A if: you think the answer was both II and III
Vote B if: you think the answer was none of the above</p>
<p>my vote: A</p>
<p>Here's my support: (under example of "interior")Math</a> tutorial: review of many-variable calculus</p>
<p>ugh this isn't going to solve anything. it's either going to a)show how many got it wrong or b)show how many got it right with no way of knowing what was right.</p>
<p>but anyway A</p>
<p>my vote is A</p>
<p>I would bet my life that the answer is A. </p>
<p>That is what i got thinking it was a pretty easy problem. Then i saw the huge debate, so i asked my dad, who has a math degree. Backed up my answer.
There is no ambiguity to the problem. Each SAT problem is checked at least 12 times by 12 different mathmaticians.</p>
<p>Good to hear that everybody so far is in concensus.</p>
<p>Aaaaaaaaaaaaaaaaa</p>
<p>Also if you look at the big blue SAT book, there is a problem that is almost identical to it on the first pratice test of the first math section. I think it is number 18.</p>
<p>Go to consolodated list of answers if you dont understand.</p>
<p>A because it said the shaded area was INSIDE y=x^2 which means (2,4) isn't included. I'm very very sure of this.. my USAMOer friend confirmed it was II and III.</p>
<p>pretty sure it's A</p>
<p>i hope this is settled now. moving on.....</p>
<p>Damn, I love what I see here.</p>
<p>A (10char)</p>
<p>BBBBBBBBBBBBBBBBBBB</p>
<p>I dont care how many mathematicians looked over the question. I, along with many others, completely understood the problem but misinterpreted "interior" (assuming you all are correct). There was inherent ambiguity in an unclearly defined term, which you needed to go on a calculus website (or ask your daddy with a math degree) to confirm its meaning.</p>
<p>i put B but i now think its A. any chance of -1 being 800?</p>
<p>B. This question was stupid.</p>
<p>Vote for A</p>
<p>I put B. The interior definition was very vague and uncatchable. These problems are supposed to be solved with a basic understanding of Algebra II. The term was never specifically defined in any of these levels of mathematics, and therefore room for further judgment. Most people at these levels would assume it meant "within". We'll reserve the exotic Calculus definitions for later. </p>
<p>Funny how it was so clear cut. I mean one or the other. Usually problems like these add up one way, but not the other. They simply got down to the two choices. "To be or not to be..."</p>
<p>What was the full problem? If i remember corectly, i put none for that one. But if someone could refresh my memory...</p>
<p>The problem gave a graph of the function y=x^2 bounded by y=4 and then gave three conditions and asked which were true. II and III were true if the word "interior" meant that points on the lines were not included, but none were true if points on the lines were to be included.
The way I look at it: why would they add the word "interior" if it didn't exclude the lines? I agree that its meaning isn't very clear, but there had to be a reason for their adding it to the question.</p>
