<p>i got (2,4) as well. im pretty sure its correct</p>
<p>but f(x)=(2,5) i think</p>
<p>(3,5) is the answer....graphing calculator confirmed</p>
<p>yeah but how did you do it</p>
<p>problem never said it was a linear relationship. It explicitly said that which one MUST work. </p>
<p>I believe your logic would not be correct if it were a quadratic relationship.</p>
<p>Im not trying to be a jacka$$ or anything but its like, im so sure that I would bet anything lol. I even remember myself thinking "if it wasnt for the negative sign, this would be so easy!".</p>
<p>Btw, for the problem of (3,5) or (2,4), can anyone word it because I remember putting (3,5) but not remember the problem so I could explain how I did it.</p>
<p>I used f(x)=2x+1 ... I might be wrong.</p>
<p>what was the 4.N one?</p>
<p>did it ask for p or x?</p>
<p>was (3,5) answer choice b?</p>
<p>Ok I think I remember the problem.</p>
<p>f(2) = 5
f(x-1) = ?</p>
<p>Well, if you take the point (3,5) and you plug it in then it will be f(3-1) which is the same as f(2) = 5 and therefore you get (3,5)</p>
<p>4.N question was 4.6 i think.</p>
<p>what was that one question, it was something like:
x+y+ab or something for all values of x and a and b are constant, did you guys get b=3?</p>
<p>Lurker- It asked for x. Which is p/5. p=23 so 23/5 = 4.6</p>
<p>it asked for the 4.6....i had to erase at first bc I put 23 as well....4.6=x is the answer</p>
<p>unfortunately it asked for x, and i stupidly put p. and it was xy not -xy; im positive. also, its (2,4) graphing calculator confirmed.</p>
<p>no b was (2,4) but i thought it was f(3) = 5</p>
<p>pall, I got b = 6</p>
<p>x^2 - 9x + 18 = x(x-3a) +(ab)</p>
<p>x^2 - 9x + 18 = x^2 - 3ax +(ab) </p>
<p>3 * a = 9
a = 3 </p>
<p>(3)(b) = 18
b = 6</p>
<p>did anyone get 88 for the largest odd integer question</p>
<p>yea 88 was the answer</p>
<p>sweatpants was that the largest prime factor question? or am i making this up lol.</p>
