Need some help with these questions, please.

Show that the function f(x) = =x3 - 2x2 + 6x has no relative extreme points. Relative extreme points exist when In this case, because the function f(x) = =x3 - 2x2 + 6x has no relative extreme points.The graph of the function has one relative maximum and one relative minimum point. Plot these two points and check the concavity there. Using only this information, sketch the graph. f ( x ) = x3 - 3x2 The relative minimum point on the graph is]. (Type an ordered pair.) Since the value of f" at this relative minimum point is . at this point, the graph is The relative maximum point on the graph is. (Type an ordered pair.) Since the value of f" at this relative maximum point is , at this point, the graph is Which of the following graphs is f(x)? O A. O B. OC. OD. 18- 734
