Sketching derivatives? ?Reproduce the graph of f and then sketch a graph of f?? ?on the same axes.

SOLUTION STEP 1 The objective is to find the derivative of the graph f.ie we have to find the slope at each point of the graph,but however only a rough estimate of the slope is enough,as finding the exact slope is difficult in this case. At the point a in the graph we can see that the slope is 0.ie f intecepts x axis at x = a. Now we can find that the graph...
