Question: Solve the given problems by finding the appropriate derivative.

A computer analysis showed that the population density D(in Person/km2) at a distance (in km) from the center of a city is approximately D = 200(1 + 5e-0.01r2_ if r < 20 km. At what distance from the city center does the decrease in population density itself 1dD/dr2 start to decrease?
