Part (a) and (?

I think you have no problem with (b ). I still figuring out what the question wants for part (a). Do you have any idea?

part b also dun know le?can u show the working?mayb taking picture

part a no idea,that why i ask u lol

(A)1 is decreasing 1 is increasing??

OALim: Do you mean by P increases when P_0 is less than k and vice versa?

For part (b ), think of the question below:
If dP/dt is the population growth, then what we can do to determine the change in the population growth?

ya～～bcoz 1-p/b～and if p less than b + p more than b -

OALim: but the question is asking about the relationship between P and k, how will you relate your increasing and decreasing P to the b?

Should be "increasing and decreasing P to k?".

sry·is k not b～discuss by consider sign of dp/dt～i think is like tat～

OALim: so you are saying that when P is greater than b, P is increasing? If so, what does P to do with k? When k is changing, what happen to P again?

k fix？？carrying capacity～maximum capacity ？？

OALim: The relationship of P and k means the condition of P when k is changing. So there must be an equation to describe such relationship.

like tat i dnknw liao
