When a bactericide is added to a nutrient broth in which bacteria are growing, the bacteria population continues to grow for a while, but then stops growing and begins to decline.
the size of the population at time t (hours) is $b = 9^6 + 6^4t - 6^3t^2$ .
find the growth rates at t = 0 hours, t = 3 hours, and t = 6 hours.
