<p>also on the erick’s curve thing…how do you calculate raw score? i know it sounds stupid…but is it with the divided by 4 thing ir is it just subtract one from 54 for the total number of questions you got wrong.</p>

<p>meaning:</p>

<p>say you got 5 Mc wrong.
is it 54-(5/4)
or 54-5?</p>

<p>I added a few more:</p>

<p>anyone remember the x=8 y=16 question? I see it on the list but cant remember it at all, im starting to panic.</p>

<p>Linger
The question was which set was NOT true for:
y^2 = x+x+x+x</p>

<p>Linger, was that the one where you figured out what the value was and the operation?</p>

<p>It was division, and the answer was 2…which I believe was A</p>

<p>The graph with the weird shape (almost like a parabola with two lines sticking out from either end) and each answer was a different graph, asking which one was a possible function of it or something.
Anyone remember that?</p>

<p>[absolute value graph y= |h(k)|]
ANSWER: D, all points are above the x-axis</p>

<p>progress</p>

<p>@wangh</p>

<p>Thanks now I remember</p>

<p>regina, I believe that one asked for the absolute value of the function. It was the graph with all points above the y=0 since the value must be positive/zero if its in the abs value sign.</p>

<p>Can anyone recite the v/x problem as close as it was on the test? Apparently the answer is 42, I just want to know the problem.</p>

<p>what was the 77 one?</p>

<p>dang… got the sq rt problem and the median problem wrong… no chance for anotha 770… :(</p>

<p>for the second gridin question, the answer was not 6. it was any value between 6 and 12, or some values like those</p>

<p>no matthew it asked for 3x</p>

<p>matthew, 6 worked.</p>

<p>yea, and x could be any value between 2 and 4, because 2x equaled to any number between 4 and 8
again, something like that.
im not saying 6 didnt work, but 6 isnt the sole answer.</p>

<p>can the 4 digit one be 9522 ?</p>

<p>@tabasaur no all numbers were differnt</p>

<p>no it wasnt 9522 because every digit was a distinct number. You can’t have two 2’s.</p>

<p>For the water changing one that apparently is</p>

<p>1:04 to 1:08</p>

<p>Is that during the rapid increase in the beginning of the graph?</p>
