The population of a colony of bacteria is modeled by the function , for 0 ≤ x, where population P is in thousands, x is in hours, and x = 0 corresponds to the moment of introduction of a certain chemical into the colony's environment. At which time(s) is the bacteria population growing at an instantaneous rate of 0, going from positive growth just prior, to negative growth right after?

Hi, @Olympiad2016! Welcome to OpenStudy! 

It might help you get your question answered if you post it in the "Mathematics" section instead. If you click on the blue bar at the top of your screen that says "English" right now, it'll give you options and you can switch to Math. :D
