Homework Help: Differential equation problem i need help

  1. Oct 4, 2008 #1
    1. The problem statement, all variables and given/known data
    A population is modeled by the differential equation

    dP/dt= 1.2P(1-P/4200)

    (a) For what values of P is the population increasing?
    (b) For what values of P is the population decreasing?
    (c) What are the equillibrium solutions?

    Do I just plug in numbers or do I find the derivative and then plug in numbers.
