<p>there werent 10 choices, it sed 'distinct' #s</p>
<p>what was the question about the symmetry.. i remember putting y intercept. not y=x</p>
<p>doh, you're right, there were only 6 possibilities, i double counted, ugh</p>
<p>the one with over 100?..i think there were only 6 choices..cause it said two DISTINCT numbers so 5 1 and 1 5 are the same..there were 4 numbers, so A B C D ab ac ad bc bd cd..leaves 6 possible selections...3 were over 100.. 3 /6 = 1/2</p>
<p>it was definitely y=x, thats the definition of an inverse function</p>
<p>did anyone figure out the last one?</p>
<p>y = x is symmetric about the origin as well</p>
<p>oo what did you guys get for number 50? it was either 5 or 8 and i guessed 8</p>
<p>789 for the question about painting walls and ceiling</p>
<p>1 - x^2
for g(x)</p>
<p>sin^2(x) + cos^2(x) = 1
so
cos^2(x) = 1 - sin^2(x)</p>
<p>yeah, i guessed 8, then changed to 5 at the last minutes</p>
<p>damn, i did the surface area of a cube ... i knew i'd make a handful of dumb mistakes</p>
<p>did anyone get 15.6 for the length of one of those triangles</p>
<p>I never really thought about it being a cone. I just automatically saw it as a volume of revolution problem. It still gives the right answer, though.</p>
<p>was the area of trapezoid 7.96... or 8.13523757575745</p>
<p>what was the answer to the one with log base 2 of that function. I kept doing it and getting like 6.9 which wasnt a choice, so i just put 6....</p>
<p>can someone explain how u can draw 2 lines so that they dont cross on x/(x^2-1). #50 was 5. the digits were 2, 0, and 3.</p>
<p>the lines x=1 and x=-1....the asymptotes</p>
<p>it was 5?? damnit!!!! you can draw lines at x=+ or - 1 b/c there are vertical asymptotes since f is undefinied.</p>
<p>right...but...if u graphed it using ur calculator...u saw that there was something in the middle there.. a weird looking thing...crossing through the origin</p>
<p>was it I & II, for the roman numeral question.. it was like sumting about f(x) and g(x) intercepting at x value, y value</p>
