The figure above shows the graph of f', the derivative of a function f. The domain of the function f is the set of all x such that - 3 < = x < = 3. For what values of x, - 3 < x < 3, does f have a relative maximum? A relative minimum? Justify your answer. For what values of x is the graph of f concave up? Justify your answer. Use the information found in parts ( a ) and ( b ) and the fact that f ( - 3 ) = 0 to sketch a possible graph of f on the axes provided below.
Note: This is the graph of the derivative of f not the graph of f.
