Dr. silas studies a culture of bacteria under a microscope. the function b_1 (t)=1200〖(1.8)〗^t represents the number of bacteria t hours after dr. silas begins her study. what does the value 1200 represent in this situation? what does the value 1.8 represent in this situation? the number of bacteria in a second study is modeled by the function b_2 (t)=1000〖(1.8)〗^t. what does the value of 1000 represent in this situation and what does it tell you about the difference between the two studies?
