This is my trouble:

$\displaystyle x^{,}=-x^{2011}+tx\\x(0)=x_{0}$

a) Show that saturated solutions (in right) are defined for any ray [0,infinity]

b)Show if $\displaystyle x_{0}\neq{0}$, then saturated solutions (in left) to blowed up in complete time and give a valution according to $\displaystyle x_{0}$

Thank you for help (sorry for error)
