Question:

a. Factorise completely x³ − 6x² + 9x.

b. Sketch the curve of y = x³ − 6x² + 9x showing clearly the coordinates of the points where the curve touches or crosses the axes.

c. The point with coordinates (−4, 0) lies on the curve with equation y = (x − k)³ − 6(x − k)² + 9(x − k) where k is a constant. Find the two possible values of k.
