SOMEONE HELP WITH CALCULUS PLEASE ;-;

Sam · February 09, 2009, 07:12:29 PM

okay so I'm failing calc if I can't finish these two more problems tonight then I'm kicked out of the clas, so please help someone ;-;

I'm jsut going to post the first one, if someone can hep me with that I'll post the second. For some reason I suck at these problems even though they seem easy.

The figure above shows the graph of f', the derivative of f.
The domain of f is the set of all real numbers such that -3 < x < 5

a) For what values of x does f have a relative maximum? why?

b) for wgar values of x does f have a relative minimum? why?

c) On what intervals is the graph of f concave upward? Use f' to justify your answer.

d) Suppose that f(1) = 0. In the xy-plane provided, draw a sketch that shows the general shape of the function f on the open interval 0 < x < 2.

Look for critical numbers first.

I can get that far, it's just that I can never remember which equation to plug into to find the positives and negatives for ifferent things, and then waht the different positives and negatives mean for it and ARGH.

a)x = 4 because the slope changes from positive to negative at that point.
b)x = -2 " " negative to positive at that point

That's weird, we just went over this today in class.

I can help you with c. Okay, this is the graph of f'. What is the derivative of f'?

Why the fuck would anyone who's not a masochist ever take calculus?

It's actually easier than statistics. Don't ask me how that works.

Required for my major.

The only reason I passed pre-cal was because I copied my friends' papers during the tests. Same goes for Algebra 2. good times.

If you ever want to do something useful, you'll need it.
