Question
Use the graph of the function f (x) below to graph f'(x), after answering the
given questions. Either use graph paper, or measure your axis markings very carefully so that
your derivative graph is neat and accurate. You don't need to copy the graph of f(x) onto your
other page, though you can if it will help!
