<p>I am self studying for the mathematics IIc test over the summer and will take it when I finish my pre-calculus course this year.</p>
<p>Could someone explain even and odd functions and refresh my mind as to how inverse functions work? thanks! </p>
<p>For reference, I am using the Barron's book to study.</p>
<p>I understand most of the math in the book save a few topics which are new to me and greatly appreciate the help!</p>
<p>[Let</a> me google that for you](<a href=“http://■■■■■■■.com/347aoxz]Let”>http://■■■■■■■.com/347aoxz)</p>
<p>and </p>
<p>[Let</a> me google that for you](<a href=“http://■■■■■■■.com/38vdxzp]Let”>http://■■■■■■■.com/38vdxzp)</p>
<p>This isnt homework hotline.</p>
<p>…thanks, but I did google it and hoped that a bright individual may have been able to better explain it to me.</p>
<p>How much better of an explanation do you need? It is pretty straight forward.
If a function is symmetric about the y-axis then it is even, if a function is symmetric
about the line y = x then its odd. If f(x) = f(-x) then its even. If f(x) = -f(-x) it is odd. </p>
<p>And inverse functions are like this. If g(x) is the inverse of f(x) then
g(f(x)) = x and f(g(x)) = x. And functions only have an inverse if they are
monotonically decreasing or increasing. That means they increase all of the time or
decrease all of the time.Thats all you need to know.</p>
<p>If you really can’t understand it from that or just by reading some of the sites that
came up on google then you probably won’t do very well on SAT Math Level 2.</p>
<p>^I understand that much but I need to understand how it works or I simply don’t feel confident about the subject matter.</p>
<p>Then do some practice problems. Inst that why you got the prep book?
I don’t see how you can go deeper than what I just explained, I mean it isnt
a very vast subject. The only way I see of someone understanding it better is
if they did some practice problems and looked at graphs of function and try to figure
it out if they are even or odd and have an inverse. Someone can’t really tell you that
you gotta do that by yourself.</p>
<p>I see your point. At least this experience was fruitful for me, Thanks. </p>
<p>I’d better hit the books now :)</p>
<p>Go to youtube. Khanacademy.</p>
<p>^^^ hey man that google thing was pretty cool. how’d you do it?</p>
<p>^You just look up “let me google that for you”, the site is probably lmgtfy or something, and then it’ll take you to a site where you type in what to look for. It will then give you a URL that google’s the info.</p>
<p>^appreciate it</p>
<p>math 2 should be a breeze. dont bother studying for it.</p>
<p>Math 2 is not a breeze. In fact it is so hard. man GreedISGood not everyone
can be as good at math as you. Claiming to have taken Ap calc ab as a sophmore
in one thread and then saying that they will take ap calc ab as a senior in a chance
thread. </p>

<p>Just look at how good he is in that thread. Ap calc as a sophomore. And take a look at
this quote from that thread GreedisGood.
"I’m taking BC Calc exam next year (will get a 5 on AB sub score and 5 on BC most likely) and i’ll take LA and/or MVC at Brown.</p>
<p>Senior year: Fourier analysis and Differential equations" </p>
<p>wow see just look at how good at math he is. taking all that math while in high school.</p>
<p>But wait what’s this?</p>
<p><a href=“http://talk.collegeconfidential.com/princeton-university/956292-chance-urm.html[/url]”>http://talk.collegeconfidential.com/princeton-university/956292-chance-urm.html</a></p>
<p>Taking ap calc ab senior year. I though you already took that? and where’s MVC or LA
or Fourier analysis and Differential equations?</p>
<p>well</p>
<p>I sense a ■■■■■. Or it’s 2 different ppl on one account.</p>
<p>Math is actually one of my finer points in the sense that I am more oriented towards calculus and algebra topics. Trig and the stuff in pre-calc, I find challenging. Even so, I have not taken Pre-calc (in school) yet, so after I do, I’m expecting an 800 on the math 2 test after a review and refresher of what i had studied this summer. Thanks everyone for their comments and opinions and thanks especially to copyxmkii, because of whom, I put in a little more effort and instead of being lazy, I actually understood odd/even functions and inverse functions.</p>
<p>^thats not my chance me thread, that was friend who did that. I’m not half-black.</p>
<p>Then why do you use the first person and why couldn’t that person make
their own account?</p>
<p>^b/c that person was over at my house one day and asked me if he had a shot a princeton. i told him i could make a forum thread online and he said ok.</p>
