## Consider set of equations

Hello! I have trouble with this set:
EX. Consider set of equations:
$x^{,}_{1}= -x_{1}+x^{2}_{2}\\x^{,}_{2}= -x_{2}-x_{1}x_{2}$
a) Show that any saturated answers are defined for all simple.
b) Show that zero solutions are asymptotically stable, when t to ascond + infinity.
c) Is zero solution is stable, when t to ascond -infinity?
(Sorry for my errors)
