Could I obtain assistance with these . problems?

1. Find the coordinates of the turning points of the curve y=3x^4-8x^3-30x^2+72x+5.

Determine the nature of these points. "Determine the nature" means to decide weather the point is a local max or local min.

2. Determine the coordinate of any turning points on the given curves. For each, decide if it is a maximum or minimum. Check you answers by using your GDC:

a) y=x^3-9x^2+24x-20

b) f(x)=9x+1/(6x^2)
