[-/0.71 Points] DETAILS 0/30 Submissions Used MY NOTES A class of models for population growth rates in marine fisheries assumes that the harvest from fishing is proportional to the population size. One such model uses the following quadratic function. G = 0.30 - 0.2n2 Here G is the growth rate of the population, in millions of tons of fish per year, and n is the population size, in millions of tons of fish. (a) Make a graph of G versus n. Include values of n up to 1.7 million tons. G 0.10 0.06 0.05 - 0.04 0.5 1.0 5 0.02 - -0.05- 0.5 1.0 1.5 -0.10 -0.02 - -0.04 O-0.15- O G G 0.15 JUL 12 GAS 35 ...
