Cut Sets in graph
Question: Number of cut sets possible a tree with 10 vertices _________ My approach : Number of edges in a tree with 10 vertices = 9. Each of these can be considered as a cut set as deleting one edge necessarily disconnects the graph. Also any combination (I mean ... cut sets = 2^9 - 1 = 511. But the answer is written 9. Apparently they are not considering the super sets. Why?

(A) -5 (B)-1 (C)4 (D) 0 Solution: f(x) = $2x^3 - 3x^2$ f'(x) = ... what will be the answer -5 or -1, as closed intervals are given, so in case of local minimum also we should consider the extreme points, right?
