<p>i got -(x+2)^2+(-2)^2 which i remember to be choice c</p>
<p>-1 in math? scaled score, anyone?</p>
<p>Thanks!
790 for -1?</p>
<p>shyam: i honestly think -1 might be an 800. i took the march one and june was significantly harder; march was -1=790</p>
<p>connie, please plug it in. both -(x+2)^2 + 4 and -(x-2)^2 + 4 have maximum values of 4, thought they have different values for x. if those were choices C and B, then both of them cannot possibly be right.</p>
<p>@Shyams: it depends. Sometimes -1 is still 800, other times it’s 770. It’s never lower than 770, so you can expect around a 780 or 790.</p>
<p>Is there actually a chance of -1 being 800?</p>
<p>@dj04x7 You read it wrong, i’m fairly positive those both weren’t answers.</p>
<p>i did. just now and during the test.
-(x-2)^2 + 4 wasn’t a choice</p>
<p>B was -(x+2)^2 + (-2)
and C was -(x+2) + (-2)^2</p>
<p>@Prettyawesome, there is a small chance.</p>
<p>i dont get what a curve means?</p>
<p>Can’t edit on mobile… anyways where a & b are horizontal/vertical stretch, h = x coord of vertex, k = y coord of vertex and therefore the value of the function at the vertex. For a parabola facing up (positive a) the vertex is the minimum so k = min value of function. But these were all downward facing (negative a) so the vertex is the maximum. Therefore you want the function with the greatest constant… 4 is greater than 2.
You can’t just plug in a random number and expect to come up with the maximum value.</p>
<p>And no one is giving you an answer because the curve changes each year and none of us actually have scores yet.</p>
<p>For the triangle question, I’m pretty sure that it was none because you can have a 3,4,5 triangle.</p>
<p>Sorry to repeat this (once again), but:
Does anyone know if 5.5 was an answer on the grid-ins? And was 3.33 the answer to the first grid in on one of the sections?</p>
<p>@black/dj</p>
<p>One of them(the correct answer) was (-(x+2))^2) if I remember correctly</p>
<p>No…</p>
<p>the triangle was equilateral. it’s factually proven. there is no other way that A + B = 2C.</p>
<p>I’m pretty sure connieshi is right about the answer choices for the parabola question</p>
<p>(-2)^2 = 4</p>
<p>If -1 is an 800, I might jizz in my pants when I see my score</p>
