In Problems $1-6,$ assume that the population growth is described by the Beverton$-$Holt recruitment curve with growth parameter $R$ and carrying capacity K$.$ For the given values of $R$ and $K,$ graph $\frac{N_t}{N_{t+1}}$ as a function of $N_t$ and find the recursion for the BevertonHolt recruitment curve.
