1.	The function f(x) = 3x2 - x3 has critical points at x = 0 and x = 2. Determine whether each of these critical points is the location of a relative maximum, relative minimum, or a point of inflection.
		A.	(0, 0) minimum and (2, 4) maximum	B.	None of these is correct.
		C.	(0, 0) minimum and (2, 4) point of inflection	D.	(0, 0) maximum and (2, 4) minimum
		Hint
	2.	Determine whether the given critical point of x = -7 is the location of a relative maximum, relative minimum, or a point of inflection for the function f(x) = x3 + x2 + 1.

		C.	minimum	D.	none is correct
		Hint
	3.	Locate the extrema for the graph y = f(x).
