A bacterial infection in an internal wound grows as N'(t) = N0exp(t), where the time t is in hours. A dose of antibiotic, taken orally, needs 1 hour to reach the wound. Once it reaches there, the bacterial population goes down as $\frac{dN}{dt}=-5N^2$. What will be the plot of $\frac{N_0}{N}$vs. t after 1 hour?
