March 2012 SAT I Math Thread

<p>@prophylaxis</p>

<p>yes it was certainly 6</p>

<p>I posted this a few pages ago and got no responses, but I don’t think the answer was 6 for the min/max one.</p>

<p>The original function f(x) that was graphed had a maximum of 4 and a minimum of -2. However, I am pretty sure the question was asking the difference between the max of g(x) and the min of the original f(x). The new max for g(x) is 6 (translated up 2 units from 4), and the original min from f(x) is still -2, so I got 8 as the difference. Anyone else get that?</p>

<p>It was asking for the difference between the max and min for g(x) only. </p>

<p>It was a trick question in its entirety.</p>

<p>@gman45: F(x) + 2 implies that the entire graph of f(x) is shifted upwards, so there would be no change…? Either that, or the question was too ambiguous.</p>

<p>Why would it ask for the min of the original f(x) and compared to max of the new f(x)? </p>

<p>I think it was pretty clear that it wanted the new max - new min, which is still 6.</p>

<p>@forsworn99
if that’s the one about the children
it was how many kids per family, so you had to take the total number of children and divide that by the total number of families</p>

<p>yeah that question was so dumb. the first time I went through it during the test I thought I read it wrong because why would they give you all that bs about defining g(x) if it doesn’t even change the shape of f(x)…</p>

<p>It asked if g(x) = f(x) + 2, what is the difference between the max and min of g(x)</p>

<p>Ah well that sucks. Hopefully I didn’t make any other stupid mistakes, everything else seems good so far.</p>

<p>was the octagon with all the angles experimental??
i had 3 25 min math sections and 1 20 min. so i definitely had an experimental i just dont know which one…
i only had one grid-in though. so either the first or the third, but hopefully the third because i thought that one was the hardest!!</p>

<p>Octagon in a square with shaded corners?</p>

<p>Yes that was experimental because 3+ people didn’t recognized it. But my experimental math section included a grid in part.</p>

<p>@niceboat there is definitely more than one type of experimental math section because some people had 2 grid in sections and some only had one but either way they still had 4 math sections…</p>

<p>no i meant just octagon with the angles labeled…i didnt have an octagon with a shaded triangle either but i definitely had an experimental math section.</p>

<p>-1 = 800 Math???
What do u think the curve will be? Was it hard or easy?</p>

<p>@fieldhockey: Was the octagon inscribed in a circle and you had to find angle x?</p>

<p>If so, then I had that section, and it wasn’t experimental because I got 4x CR.</p>

<p>I say 2+2= 4 and that SAT is a waste of time and money</p>

<p>EFF Collegeboard</p>

<p>if -1 is 800, then is -2 going to be more like 750 or 790?</p>

<p>more like 770</p>

<p>I don’t think -1 will be 800 for math, it wasn’t THAT difficult, i think -1 will end up being 780.</p>

<p>I have a few questions (17-20) on one particular Math section - perhaps it was experimental?</p>

<p>I had a question on gas mileage and the amount of gas that you have - it had variables, m, r and g. It was #20 on the section (last question).</p>

<p>Another one I had trouble with was an inequality (17?). It went something like the absolute value of (c + 5) > 3, and (c +6) <5 or something like that. The choices were “how many values fit c” I believe. </p>

<p>Was this section experimental? No one has mentioned them yet.</p>
