If rmax is doubled, how would the population growth rates change? If is doubled, how would the population growth rates change? The population growth rates would be half of what they were. The population growth rates would be unchanged. The population growth rates would double. The population growth rates would be four times what they were.

As per the formula of population growth is r = rmax [1-(N/K)] in a logistic model, the population growth rate ''r'' is directly proportional to the ''rmax'' . So, if rmax is doubled, the population growth would also be doubled and vice versa.
