<p>I’m pretty sure the symmetry with respect to x=3 was -1.</p>
<p>Hey what did you guys get for the standard deviation question about test scores? I picked the one with one bar sticking out.</p>
<p>why was the integer 42 thingy -6</p>
<p>imthealexx thats rite</p>
<p>dawgy, 36- -6 = 42</p>
<p>that was one of the problems i missed, and i cant believe i missed it *** lol</p>
<p>Andrearoma:
Now that you mention it, I think you have the right answer, but the answer choice was just the y-coordinate. They gave you f(-1)=1 and you had to find f(7), so it was 1.</p>
<p>am i rite about the parabola?</p>
<p>They gave us f(-1)=-1. Ergo, f(7) = -1.</p>
<p>I only finished up to #38 </p>
<p>shooting for at least 600 :S</p>
<p>I don’t remember if it was -1 or 1… I think it was how hiking wrote…</p>

<p>Your parabola method seems like a complicated method, but it does work:
y = (x-3)^2 + c
1=(-1-3)^2+c
c=-3
y=(x-3)^2-3
y=(1-3)^2-3=4-3=1</p>
<p>@ prospective you’re right. Also what exactly was the multiples one? perfect cube or something. I omitted three and so far have missed three. What is my scaled score so far?</p>
<p>@pch340 I aimed for a 600 in November, pleasantly got a 670
Now I’m aiming for a 720</p>
<p>does anybody remember the answer to the question that was like what interval does sinx ≤cosx or something> I put 0≤x≤45 degrees</p>
<p>that’s what i got slakaa</p>
<p>It was -1, -1, and then they gave you x=3. So by that reasoning it would be -1… Somewhow I miscalculated the distance from -1 to 3 and 7…</p>
<p>im doing some review homework for calc and i was wondering if anyone could help me with this thing that has been bothering me. </p>
<p>do the ends of a closed interval have limits?</p>

<p>Sorry to be sort of off topic but exactly how much harder is the AP Calculus AB test compared to the SAT Math 2?</p>
<p>What was the entire / approximate question that had to do with x= -3?</p>
