Finding where is a good start. This where the stationary points are. In between these are where the function is either increasing or decreasing, take some test points to find this out.
Okay so here is the deal.
I have the function.
G(x)=(x^3-1)^3
G'(x)= 3 (x^3-1)^2 * 3x
And i need to find out where the function is increasing and decreasing. I know how to do that, I have to set it to zero to find the critical numbers. However, I have two questions I guess. One being is my first derv right, and then if it is....how to i solve for zero. Should I divide by 2x?? then 3?? I am confused.
