<p>@saksky: the problem had f(x) and g(x), and there was a dot between them, not a plus sign. If you multiply f(1), which is 6, by g(2), which is 1, you get 6. no? anyone?</p>

<p>can someone confirm that the parabola x intercept was (5,0)? I had 25 seconds to do that problem and it was an educated guess…</p>

<p>@Xanonymous2010 Not to burst your bubble but I believe they said it was a integer in the beginning.</p>

<p>EDIT-santeria, it is (5,0) cause (3,0) wasn’t an option choice.</p>

<p>g(2) was 1 and f(1) was NOT 6.</p>

<p>f(3) was 6</p>

<p>f(3)*g(2) = 6</p>

<p>x = 3</p>

<p>ya it was (5,0)</p>

<p>For the k one, was one of the answer choices 0? I know it’s not right, but I’m just curious. Or were they all K +/- something?</p>

<p>Frenchwarrior, like I said, I don’t remember the exact question exactly. It was either 1 or 3, I don’t remember. All I remember is that you had to look at the Y values to get the answer. f(x) means Y.</p>

<p>cna someone please explain the remainder</p>

<p>You can plug in numbers, or use the modulus function</p>

<p>@Xanonymous. pretty sure it said, for an integer n. or are you just messing with our heads?</p>

<p>Grid-In answers:</p>

<p>5, 23 , 11, 17
1520
53/5
6
2
15
110
16</p>

<p>2 more?</p>

<p>I put II & III because of 4. 4 isn’t divisble by 8.</p>

<p>substitute x.
k= X^2 - 12
(x-4)(x+4)</p>

<p>k=4^2-12= 4
(4-4)(4+4)=(0)(8)=0
Answer: k + 4</p>

<p>k=8^2-12=52
(8-4)(8+4)=(4)(12)=48</p>

<p>i dont remember this: -21 is value of z when r is 7</p>

<p>“53/5”</p>

<p>What was the question for that?</p>

<p>BTW, since we all seem to be conflicted on the k problem, just plug in numbers and the answer is clear.</p>

<p>Make x=5, so 5^2 - 12 = k = 13.
(x-4)(x+4) = (5-4)(5+4) = 9</p>

<p>13 - 4=9
The answer has to be k-4.</p>

<p>For some reason I think I put down 0… But I can’t for the life of me remember why/how.</p>

<p>Well after reading all 27 pages, I’ve come to the conclusion that I suck at life, Tanya’s a ****ing whore, and I suck at reading problems correctly.</p>

<p>lol Tanya was the weirdest question Ive ever seen</p>

<p>@ masjebuto 53/5 is the same as 10.6</p>

<p>

Question was something along the lines of. 2r - 5r = Z. What does Z equal when R is 7. </p>
