<p>Math: When is it the right time to use permutations and combinations on questions? Is it usually apparent what functions to use?</p>
<p>What makes a function move up, down, to the left, and to the right?</p>
<p>Writing: Can "Like" be used in the beginning. I remember reading in a prep book that there's always a word that, if put in the beginning of the sentence, is wrong. It's not "since", right?</p>
<p>Function goes up when you add to the overall function or subtract to go down. The Function shifts to the left when you add to the x value and shifts right when you subtract from the x value</p>
<p>Hey Smith, <a href="http://talk.collegeconfidential.com/sat-preparation/425680-function-help.html%5B/url%5D">http://talk.collegeconfidential.com/sat-preparation/425680-function-help.html</a></p>
<p>I am concerning exactly the same trouble, the problem there shall turn into a useful illustration.</p>
<p>like can be used but only in certain cases.</p>
<p>for example: "Like a caveman, he eats raw meat." is fine. "Like, she's totally wearing the same dress as you." is not okay. so if you are comparing something, its okay, but if its just a "filler" word like um then its wrong.</p>
