<p>Grahams- yes, I got 0<=y<=4</p>
<p>how many years did it take to get to 100000 and how much money after 4 years?</p>
<p>i put 16.1 or something for the 100000 one and like 656 or something for the 600 one</p>
<p>^ what was the question for the range question?</p>
<p>the 4 years money was 500something, not 656.</p>
<p>ah one more waht was teh one with subbing in -x and owuldnt change the function? i thought it was fairly easy just
x^4..x^2.. but i was rushing and it was in the back.. maybe i didn read the question carefully enough</p>
<p>I think the answer was C for that one.</p>
<p>^lol, that one was amazingly simple, actually. Simple fraction problem. Put a 2 in, it doubles it.</p>
<p>Other than that, it was hard as hell. I hate planar geometry, btw.</p>
<p>^ It was mostly a joke, in terms of concepts used. But I couldn't do it fast enough =/</p>
<p>I think it was the one if x^5+x^3+x or similar to that</p>
<p>dang. i had put in the 2 for z score, but changed it last minute!! >:|</p>
<p>^Yep, because then it would multiply through by -1, which when the function is equal to 0 doesn't change anything...</p>
<p>do you guys remember a question that resembles something like this</p>
<p>f(2x) = 2 or something idk f(1/2)= ? ---> find the ?</p>
<p>ahhh why was it x^5...x^3?</p>
<p>alexkaye,
i put sqrt(x)</p>
<p>i think I put 1/2x^2 for that one... crap
but i think i put 1/2 for the one on the top</p>
<p>the range can be a set of values. for example {1, 2, 3, 4} can be the range of some function f(x)</p>
<p>i'm not positive though.</p>
<p>LIST:
f(2x) = 2 or something idk f(1/2)= ? ---> f square root x
cos^2x
Amp. 5
12pi (for the SA one)
500$ after 4 yrs
x^5...x^3</p>
<p>parabola
N (logs)
Z x2 (z score, standard deviation)
I & III (i forgot the q though)
Line and point
I&IV
The circumference one- a little over 15 (..i think?)
0<=y<=4
sovle for x ½
16 years to get to 100000
(1)=2 and f(x)=1-1/f(n) when x is greater than or equal to 1? [1/2, 2]</p>
<p>other q i rmembe rbut dont remember answers:
area of a the 30 60 90 triange.
law of sins q, what was asnwer</p>

<p>12) x = -3
49) z score and standard deviation problem: [it doubles]
50) (1)=2 and f(x)=1-1/f(n) when x is greater than or equal to 1? [1/2, 2]</p>

<p>whats the question for x=-3</p>
<p>*the range can be a set of values. for example {1, 2, 3, 4} can be the range of some function f(x)</p>
<p>i'm not positive though.*</p>
<p>I think it that case though, the range would just be 1-4 since it includes 2 and 3.</p>
