Consider the function shown in the graph below.

(Note that you can click on the graph to get a larger version of
it, and that it may be useful to print that larger version to be able to
work with it by hand.)

Carefully sketch the derivative function of the given function (you
will want to estimate values on the derivative function at different
values as you do this). Use your derivative function graph to
estimate the following values on the derivative function.
