A. Given the graph of a function y = f(x), explain how to use the graph off to determine what the graph of its derivative looks like. You should explain how to determine where the graph of the derivative lies above the x-axis, below the x-axis, and where it is zero. Also explain how to tell where the values of the derivative are large in magnitude and where they are small in magnitude and where the graph of the derivative is increasing and where it is decreasing
