<p>I put A. I think that was distance of x = 3 or x > 3 or something like that</p>
<p>abs(x+3)<5</p>
<p>I don't remember the the exact answer to the abs question, but it was along these lines:
....x ... -3 ... less than five.</p>
<p>The answer for |x+3|<5 was "the difference between x and -3 is less than 5".</p>
<p>The equation is of the form |x-y|<z, which is read as the difference between the two numbers x and y (positive number only) is less than z. Since it is x+3, y=-3.</p>
<p>What was the answer to the equidistant from two lines question? I put y=2x.</p>
<p>i put 2x as well</p>
<p>Also, the one with the weird graph where y=f(x) and holes in the graph were at y=2 and y=7. It asked what is f. I put all real numbers between except 2 and 7.</p>
<p>The answer to that polar equation problem was A, (-1, -5pi/4), right?</p>
<p>Do we have a definitive answer for f(100) witht the graph that looked like a castle. I think I had the greatest y-value possible</p>
<p>for f(100) i put 1</p>
<p>I had y=2X as well</p>
<p>For the weird graph I think I put all values between 2 and 7. Even though the graph was open at 4 at some point, it did include 4 at some points. So i had the same as hockeyfan for that one.</p>
<p>It was between 1 and 7, not 2 and 7.</p>
<p>for f(100) i put 1 as well</p>
<p>f(100) was 3</p>
<p>for f(x) and the continuity, the function was defined for >-2 and <6.</p>
<p>the answer to that one E, i can't remember what E was though. . .2 and 7, or 1 and 7. . .one or the other.<br>
they were asking for F, not x, remember.</p>
<p>Do we have a definitive answer for f(100) witht the graph that looked like a castle. I think I had the greatest y-value possible?</p>
<p>It's 1. I sat there and counted 100... TRUST ME it's one. There was probably a quick, mathematical way, but I was bummed out after chem, it's 1.</p>
<p>yeah neobez I had E as well for that one - cant remember exactly what it was though.</p>
<p>Yay! It seems as though I did much better than I thought on this!</p>
<p>It's hilarious though. I've always gotten straight A's in Pre-calc and AP calc and yet I never learned circles, polar coordinates, standard deviation... I feel as though I did horrible. What would 36-39/50 be?</p>
<p>the F(100) one you could use a simple pattern when you observe the periodic nature of the problem the period starts at x= -3 and ends at x=4, hence a period of 7. you rewrite F(X+3) because that takes into account the shift along the x axis. Plug in the N value (100) and then you get a fraction. take the whole number you get and multiply by the period of 7 and then subtract that number from the N value (100). then just count that many spaces from the X=0. the answer is 1 by the way.</p>
<p>did anyone on question number 33 get totally confused up the wazoo by the wording on the problem. it said something like if x, y and y=x then which is true and 4 were true and one was wrong. i got totally confused, reread the problem over and over and still couldnt figure it out. i thought ETS might be wrong or maybe I am stupid (more likely the latter). Just wondering what the comments in this board might be post-SAT 2Cs</p>
