    Derivatives and Graphing

    My computer illiterate teacher assigned these primitive and horrible online quizzes... it seems that whatever combination I select I can never get the right answers. The site does a horrible explanation of the concept and never explains why the problem is wrong and only checks the first wrong question, making it impossible to check the others.

    Can anyone help?

    Well, a point of inflection is where the concavity changes, so for that first link you posted the points of inflection would be found at A, C, E, and G.
    Local maxima are the maximum points which are B and F.
    f'(x) is increasing at point E. You would find this by graphing the derivative of the function and seeing where the slope increases.
    I couldn't get the right answers for the question where f(x) decrease
    But the rest after that, are pretty easy.
    Hopefully this helped; ask if you need more help!

    It's not appropriate to ask members to do your on-line quiz.

    If you want help understanding concepts like concavity, point of inflection, increasing and decreasing functions etc. I suggest you ask in a new thread and be more specific in what you don't understand.

    Thread closed.
