Consider the differential equation $\frac{dy}{dt}=18y-3y^2.$

Use a phase$-$line analysis to find the long$-$term behavior of $y(t)$ for each of the following given initial conditions. If the answer is infinite, enter oo for $$ or $-$oo for $-.$

If $y(0)=-1,$ then as $t$ increases $y(t)$ approaches

If $y(0)=0,$ then as $t$ increases $y(t)$ approaches

If $y(0)=3,$ then as $t$ increases $y(t)$ approaches

If $y(0)=6,$ then as $t$ increases $y(t)$ approaches

If $y(0)=9,$ then as $t$ increases $y(t)$ approaches
