Help 13.4: graphing exponential functions with base e 1. use graphing technology to graph the function defined by f(t) 50 e(0.25t). adjust the graphing window as needed to answer these questions: = a. the function f models the population of bacteria in t hours after it was initially measured. about how many bacteria were in the dish 10 hours after the scientist put the initial 50 bacteria in the dish? b. about how many hours did it take for the number of bacteria in the dish to double? explain or show your reasoning. 2. use graphing technology to graph the function defined by p(t) = 192 • e(0.014t). adjust the graphing window as needed to answer these questions: a. the equation models the population, in millions, in the u.s. t years after 1964. what does the model predict for the population of the u.s. in 1974? b. in which year does the model predict the population will reach 300 million?​
