Function Problems..

<p>yea for some reason when i get to a function problem i feel like im reading another language...anyone have any advice/books that would help?</p>

<p>Do you have a TI-89 Titanium?</p>

<p>I never understood it, but my calculator does!</p>

<p>^ haha. The biggest thing for me was probably my precalc class. That really solidified my knowledge about all kinds of things, from functions to graphing conics and stuff like that. <em>worships teacher</em></p>

<p>whenever you get a function problem on the SAT, realize that they give you enough information to solve the problem. Do you understand what a function is? if not, then start there. </p>

<p>Here is a sample function problem just for fun:</p>

<p>If f(2) = 1 and f(12) = 10, then what is f(7)?</p>

<p>That's unsolvable, unless you state that it's a linear function. Could be parabolic, exponential, etc.</p>

<p>it was on the kid's SAT who I tutored yesterday</p>

<p>lets assume its linear</p>

<p>you have to state what f(x) is</p>

<p>no....that information was not given on the SAT question. It just gave you what I posted up there. and it is solvable.</p>

<p>No, you don't have to give f(x) if it's linear. The problem is that you have to find what f(x) is, then plug in 7. Or you could do it with a proportion, I suppose.</p>

<p>bingo...thecomisar. This was like the last one in the math section.</p>

<p>You're KIDDING. That is so easy!</p>

<p>I hate the way CB ranks problems... the ones I have the most trouble with are almsot always level medium, whereas the "hard" ones at the end are no problem.</p>

<p>is it 6 (x10 chars)</p>

<p>what does (x10 chars) mean? i see something like this all over the forum, lol</p>

<p>if its linear won't it be 5.5?...just using slope</p>

<p>^ Yeah, 5.5</p>

<p>(x10 chars) - There is a 10 character requirement to post on CC.</p>

<p>alright thanks</p>
