SAT math annoyance

<p>i have a problem with those math questions that are like the graph of y= f(x) is shown above, which of the following could be the graph of y= 2f(x)</p>

<p>i almost always get these questions wrong, does anyone know the rules or how i can overcome these?</p>

<p>I think you are talking about function transformations. [Transforming</a> Functions](<a href=“http://www.regentsprep.org/Regents/math/algtrig/ATP9/funclesson1.htm]Transforming”>http://www.regentsprep.org/Regents/math/algtrig/ATP9/funclesson1.htm)</p>

<p>Also, look into rigid transformations of functions(where you add constants either to the function or to the argument).</p>

<p>I think it just like umm… make every points twice higher(above y axis) or twice lower(beyond y axis)</p>

<p>thank you Egghead2400, that clears up everything :)</p>

<p>grrr now i have a new problem…im doing stupid mistakes that are keeping me from getting at least a high 700s-800 whenever i look back at the problems i got wrong i always left something out that made me choose the wrong answer >.< this is really irritating me b/c i know i can get a 800 and i tried to concentrate on the questions more to make sure i didnt leave anything out but i still AM leaving stuff out </p>

<p>what should i do??</p>

<p>If you finish the math sections early, slow down. This helped me, although I did get one wrong on my SAT. Nevertheless, I escaped the terrible situation of making 3 silly errors. Try to slow down and whenever you get an answer check the q. and make sure you answered what it asked for.</p>

<p>its working, but im still making silly errors for like 4-6 problems : ( ahhhhh march SAT is coming up. im really worried i wont be able to pull off a perfect 800 for math…</p>

<p>if anyone has had 800s on that section please share your story, i need inspiration</p>

<p>From my post in another thread:</p>

<p>Math-Go slowly and use your calculator for EVERYTHING. If you’re good enough at math, you will be able to figure out what to do in about 15 seconds, then write out the numbers/steps and do the rest on your calculator to avoid arithmetic errors that could come up if you go by hand.</p>
