SAT Math sections... Functions were last year...?

Test Preparation SAT Preparation

<p>Hey I'm new here.</p>

<p>I keep messing up function questions in the math section. Im studying for the sat on may 7th and I don't remember much from sophomore year Alg II. </p>

<p>Basically whenever a question like f(x) given blah blah what is blah blah or which graph does this translation comes up I HAVE NO IDEA.</p>

<p>My problem: I got two weeks to cram 20 chaps of AP BIO and review for the test, Review for hopefully a 5 on the AP STATS test and I suck at both functions in SAT MATH and SAT CR.
I am functioning at "Maximum capacity" by studying from when I get home from track untill I go to bed.</p>

<p>What I want?: Is there a resource better than the Blue book on explaining all the function knowledge I need to know that will not take up more than say 3 hours to learn most of it? Maybe something online? </p>

<p>And... </p>

<p>What are the best suggestions for CR on the SAT? On my act practice tests I scored about 30-31, when I took the ACT I got a 25 :<. 11/18 on the subscore literature and art or something. I know the two tests differ but I am very disappointed in that. Maybe I need a better strategy? </p>

<p>Extra info: I can study for the SAT about an hour a night until May 7th, that is about the most time I can commit to it (unless trying to get into Northwestern, Duke and the like is easiest by focusing more on SAT instead of getting credit for the AP tests).</p>

<p>THANK YOU FOR ANY COMMENTS / TIME YOU SPENT ON THIS HUGE POST!!!!</p>

<li><p>For the Critical Reading, try searching “how to attack the critical reading section effectively” on google and finding the appropriate page. I found it very helpful, but of course your personal practice has to supplement the advice given.</p></li>
<li><p>Say you have f(x). f(x+1) would shift everything one point to the left, because for each x-value, you’re going to get reach the original y-value earlier than on the original graph, because you’re plugging in x+1…you don’t need to go to as high for x to get the same y-value <— think about it. Use your calculator and graph x^2 and (x+1)^2 if you need visual assistance (you should).</p></li>
</ol>

<p>I don’t know where you can learn about functions, but you could try searching Khan Academy and see if anything comes up.</p>

<p>f(x+1) shift left 1
f(x-4) shift right 4
f(x+2) -4 shift left 2 and down 4
f(x) +3 shift up 3</p>

<p>if f(7)=A, than THE VALUE OF Y WHEN X EQUALS 7 is A</p>

<p>so f(a+4) = 5 means that Y will equal 5 when X=a+4</p>

<p>Most function questions depend on you knowing the above information cold. That really is all there is to those questions.</p>

<p>Sweet thanks! I guess I just missed the definition of a function when I was doing it last year. I’ll try to use other sat books to look at what kind of problems they have on it and go from there.</p>
