$1)$ how should find phase line how should should i know when is equilibrium point is stable unstable, semistable.

Consider the following autonomous equation:

dy$/$ dt $=($e$^$y $1)(4$ y$^2)($y $3)^2$

$($a$)$ Find the equilibrium points

$($b$)$ Draw the phase line

$($c$)$Classify the equilibrium points as stable, semistable, or un$-$

stable.

$($d$)$ Suppose y$($t$)$ is a solution to the initial value problem

$($dy

dt $=($e$^$y $1)(4$ y$2)($y $3)2$

y$(0)=1/5$

$,$

Find limt$$ y$($t$).$ Justify your answer.
