so the question asked for “intersect” and NOT crosses?</p>
<p>I think it said crosses</p>
<p>Yeah, it was definitely intersect, and therefore the answer was k<=0. End of discussion.</p>
<p>I personally remember it as intersect.</p>
<p>It was intersect, but even then, when you graph the equation and find points of intersection between X^2 and y=0, there are none. K<0</p>
<p>If you make x equal to zero, and k=0, then y=0 as well. You would have the line y=0, which is the x-axis, which intersects an infinite amount.</p>
<p>BTW: I graphed it, First Curve: y=x^2, Second Curve: y=0. Used 2nd - Calc - Intersect, found the intersection at (0,0). It intersects. If x=0 k has to be 0 to make y equal to 0.</p>
<p>@nigcruch I did the same but my calc is telling me error: no sign change, how did you get your result?</p>
<p>@andro</p>
<p>actually when u graph x^2 it does intersect</p>
<p>for the first curve, go 1 to the left of the y axis and for the second curve go one to the right of the y axis. For the guess, go to (0, 0). It does show the intersect</p>
<p>Oh ok I got it, damn it I got that one wrong.</p>
<p>ughhh Im so anxious to see how I did</p>
<p>does anyone remember what the question for this “167.6” was?</p>
<p>So you do not remember anything about the question?</p>
<p>167.6 was supposedly an answer to a question</p>
<p>I dont seem to remember ever putting that. Do u happen to know what the question was for that?</p>
<p>ummm i think the answer should have been like 153 or something instead of 167 right?</p>
<p>it was the question with a right circular cone of diameter 8. i think the lateral height was 10 not the actual height?</p>
<p>Agreed. November’s test was waaaay too easy.</p>
<p>for the intercept question to finally put an end to this discussion (without any calculus lol :P) “intercept: The value of x on a graph when y is zero (0). (a, 0)”. In y=x^2 + k even if k = 0 there is a point where it is in the form (a,0) i.e. (0,0). hence it has to be k <=0.</p>

<p>any guesses where wld a score of 38/39 put me??</p>
<p>this test was hard there should be a huge curve</p>
<p>it wasn’t even…hard. I didn’t study and still do it good. Easiest math test ever tbh</p>
<p>I guess an easy test doesn’t make us lucky. It is obvious that the curve won’t be as lenient as usual, but can any of you predict just how much harsher it will be?</p>
<p>maybe 45 = 800
44 = 790</p>
