<p>why wasn’t it B though because that graph also had 3 intercepts but they were all positive while E had two positive and one negative intercept?</p>
<p>hm. The answers were all numbers between like 1 and 6 tho. 599 is way too large. I was stuck between 5.2 and 6.0.</p>
<p>Wrong question then.</p>
<p>holy crap there was something with 3 positive intercepts? ****, i thought there wasn’'t any graph at all with more than two intercepts besides E</p>
<p>what did everybody else get?</p>
<p>It’s because graph B had both sides leaving the coordinate system in the same direction whereas graph E had one side leaving the coordinate system upwards and the other leaving the coordinate system downward.
because the function was (x-a)(x-b)(x-c), that meant it was a third degree polynomial and when the degree of a polynomial is odd, it means the ends of the graph face in opposite directions, up and down. its an obscure rule…</p>
<p>there was one with 4, but E was the only one with exactly three intercepts, i dont know what sporty is talking about.</p>
<p>one graph had none, one had one, one had two, one had three, one had 4 from what i remember</p>
<p>no jansat, you got it right. It was E for the reason that I explained above.</p>
<p>Ya I concur with gildemushroom…so was the answer for that E?</p>
<p>what would be an approx score for 5 skip and 3 wrong?</p>
<p>@sporty</p>
<p>780-790</p>
<p>Sporty it depends on the curve, which is hard to determine. 5 skipped and 3 wrong might not be an 800 though. I can’t for sure tho.</p>
<p>I think I’ve answered a lot of questions and would really appreciate it if someone would give me a definite answer on the quadratic regression question involving the ball being thrown.</p>
<p>Your equation seems right though… I remember the C term had to be 1.5… weird. I’ve been wondering about this question for a while</p>
<p>i left that one blank, sorry gildedmushroom
i remember the numbers in the table, but i dont know how to work quadratic regression problems</p>
<p>Yeah me neither. I really thought I had studied everything too. Apparently you need a ti89 for regressions. I limited the choices down to 5.2 and 6 and just guessed 5.2… hopefully I don’t regret that…</p>
<p>hey should we try to remember the questions from the beginning to the end
i think that would be the most efficient way.</p>
<p>True. I recall that #1 was the product, reciprocal, square one. Where the product was something like 15126. The answer was definitely 123.
The next one they gave you y = mx + b and wanted a parallel equation.
The answer was y = mx + 2b.</p>
<p>I don’t remember the third problem</p>
<p>can anybody tell me what they got for the question with the Roman numerals…
I. cos 2theta is greater than sin theta
II. sin 2 theta is less than…
III. tan theta is greater than sin theta.</p>
<p>there was an abs value quest in the beginning, i got -5<x<0</p>
<p>I couldn’t remember the questions in order…but then there was this question that says something like “If p is a prime #, then the equation is ‘bla bla bla’” what was the answer to disapprove that statement?</p>
