E. Smith has studied population growth for the water flea. Let N denote the population size. In one experiment, Smith found that G, the rate of growth per day in the population, can be modeled by the following function. G.0.44N(228 - N) 228 + 3.46N (a) Draw a graph of G versus N. Include values of N up to 350. G 15 15 10 10 50 100 150 200 250 300 350 50 100 150 200 0 300 350 -5 -5- -10 -10 o-15 -15 G.
