Which of the following graphs is the solution to the logistic differential equation dydt=y5(1−y500) \displaystyle \frac{dy}{dt}=\frac{y}{5}\left(1-\frac{y}{500}\right)dtdy=5y(1−500y) with the initial condition y(0)=100y(0)=100y(0)=100 ?
A logistic differential equation has the general form:
Since we know the carrying capacity (L=500L=500L=500) and the yyy-intercept (y(0)=100y(0)=100y(0)=100), we can pick the graph which reflects this.
