    Graphing Problem

    Okay, so I understand how to draw a graph of a function given the graph of it's derivative. I can do that part. However, I DON'T understand how to graph a first derivative based on a graph of its second derivative.

    If anybody could show me just that one half of the question, and explain how you did what you did, that would be really helpful to me. I have trouble understanding how to graph things in this way.

    Here is the problem:





    Basically, I just need help drawing f\prime(x). Once I have that, I already know how to graph f(x) from it!

    Thank you!

    you have the same relationship between f ' and f " as you do between

    f and f ' as f " = (f ' ) '

    If you want think of f ' as a fn g and f " as g '

    Oh really?! Wow! Yeah I graphed it the same way I would do it with f ' (x) and f(x) and sure enough it worked out with my answers!



    Thank you SO much!
