Math Question

<p>Alright, I always hate these SAT function questions- I never understand them. This question is from pg.369 of the #1BB (Practice for Math)</p>

<p>The figure above shows a portion of a graph of the function f. If f(x+5)=f(x) for all values of x, then f(x)=0 for how many different values of x between 0 and 12?</p>

<p>(A) 8
(B) 9
(C) 10
(D) 11
(E) 12</p>

<p>Any help here would be appreciated!</p>

<p>Alright the image didn't work out too well-sorry about that, but is there a way to solve the problem without it?</p>

<p>Wow, thanks- do you have some sort of database for these questions?</p>

<p>^haha I was also wondering this, so if you may indulge this info upon us, xiggi...</p>

<p>Xiggi has enough years of experience on CC to know that just about every question has been asked and answered before.</p>

<p>Also, he knows how to use CC</a> Search.</p>

<p>There is a "database" although I don't think that's where xiggi found those posts. If you need any more explanations, go to <a href="http://talk.collegeconfidential.com/sat-preparation/763933-new-feature-best-sat-prep-forum-faqs-please-read-before-posting.html%5B/url%5D"&gt;http://talk.collegeconfidential.com/sat-preparation/763933-new-feature-best-sat-prep-forum-faqs-please-read-before-posting.html&lt;/a> which is stickied and under "Consolidated Answers" pick <a href="http://talk.collegeconfidential.com/sat-preparation/339734-consolidated-list-original-blue-book-math-solutions.html%5B/url%5D"&gt;http://talk.collegeconfidential.com/sat-preparation/339734-consolidated-list-original-blue-book-math-solutions.html&lt;/a>. Then use Ctrl + F to find the explanation you're looking for.</p>

<p>The searching part is pretty simple. Just type in the page number into the keyword field, narrow the scope of the search to "SAT and ACT Tests & Test Preparation" and hit search. You might want the results shown as posts though, instead of threads, since some threads make you comb through pages to give you what you're looking for. The panel for that option is probably somewhere near the bottom.</p>

<p>I happy someone noticed that I have been copying the links to previous answers on purpose as opposed to copy the answer itself. </p>

<p>I do, however, rely on a different tool, albeit related. I found it is easier to use the google bar in IE and copy a section of the question. I do two searches: one for "this site" and then one for web. This usually leads to the previous answers of CC. </p>

<p>As everything else in the SAT, it's all about finding easy solutions. :)</p>
