Hi to all.

Okay, this is a small and simple question, but I just need some help understanding it.

Q) The equation of a curve is y=6x^2-x^3. Find the coordinates of the 2 stationary points on the curve, and determine the nature of these stationary points.

This was part 1 and solved it, getting points (0,0) min and (4,32) max.

However, in part 2, it tells us to state the values of x for which 6x^2-x^3 is a decreasing function of x. Do I have to use the x values found in part 1? And if so, how do I structure the answer?

Thanks for your help.
