Please help the equations are dy$/$dt $=$ y$^2($y$+2)($y$+1)$ And dy$/$dt$=($y$^(2)-1)($y$+3)$

$f=$@$(y)y***(y+3)$;

phaseLine$(f,-5,5$;

$2.$

figure$()$

$\%$ Phase line for the first equation

$f=$@$(y)y^2,**(y+2)***(y-1)$

$f=functio{n}_h$andle with value:

@$(y)y^2***(y+2)***(y-1)$

$f=$ function$\_$handle with value:
