<p>For questions thta involved with volumes, can you just write the function notations? Like g(x) or f(x) instead of writing the entire function out?</p>
<p>I think you usually can just write f(x) or whatever. In question 2 I think that they might have written it out because it was differential equation. Im not going to chance it on the test though</p>
<p>If it’s defined in the problem, then yes.
but make sure you don’t always write f(x). if the function given by the test is R(x), write R(x)! i always make that mistake =[</p>
<p>You should look at the scoring guides. They tend to be pretty clear about what has to be shown, and you can detect some patterns if you look closely.</p>
