<p>what about the one where it was how can u find if f(x) and g(x) are equal. I put II only, but i think i read it wrong. which one said that you need to find the y-coordinates? i thought it was the second, but earlier posts said it was the first.</p>
<p>i left that one blank... so freaking mad...</p>
<p>the ln one</p>
<p>I was the x-coordinate, II was the y-coordinate, and III was finding the zeros of f(x) - g(x).</p>
<p>What was the answer anyway? I think I might've missed it in this thread.</p>
<p>i thought it was II and III, but that wasnt an answer, so i just put II, but before people were saying it was I and III. but i didnt see how I could've been it. anyone know what it was?</p>
<p>What do you think the curve will be?</p>
<p>it was kinda hard....hope the curve is generous</p>
<p>What did you guys put for the question with rotating about the x axis?</p>
<p>I was definitely an answer, I thought. II could lead to the answers (plug in the y values, solve for the x values, which are really the answers), and III I think gives you the answers as well. I made up two equations and plugged in the different scenarios and I think I got the same numbers for I and III, so that's how I figured it out.</p>
<p>aqua rocket, do u remember the ?</p>
<p>was an answer 2f(x)-g(x) > or equal to 0
whats a score of 4 blank 3 wrong</p>
<p>Roman numberal I and III are both true to find a solution. If two values are equal, the difference between them is 0.</p>
<p>hurdlesrock...are you talking about the question with the graph of f(x) and g(x) and the question is which expression is greater than 0? For that, it was g(x)-f(x), because the f(x) values are always smaller than the g(x) values. I just plugged numbers in.</p>
<p>i can't remember..but i think i put down 0 for the lnx and e^-x one...and for the plane one..i put infinately many lines T____T</p>
<p>There two questions about graphs with I, II, and III choices I think. One had an actual picture of f(x) and g(x) and the other was about graphical ways to find solutions.</p>
<p>The one that I was talking about was the graphical ways to find solutions; I think hurdlesrock is talking about the other one. I can't remember what the answer/question to that one is, although I do remember putting SOMETHING down.</p>
<p>the lnx was .27. trust me i checked on my calc.</p>
<p>Do you guys think today's test was harder/easier than the test in the REAL Subjects dark blue book?</p>
<p>really? ln(0.27) is -1.3, and e^-0.27 is 0.76 though</p>
<p>yea, i got .27 as well</p>
<p>I third the .27. what'd you guys get for the recursive equations?</p>
<p>Listen LN x = .27
e ^ .27 = X</p>
<p>E ^ (- E ^ .27) = .27</p>
