Dr. garcia studies a culture of bacteria under a microscope. the function b_1 (t)=1100〖(1.7)〗^t represents the number of bacteria t hours after dr. garcia begins her study. what does the value 1100 represent in this situation? what does the value 1.7 represent in this situation? the number of bacteria in a second study is modeled by the function b_2 (t)=900〖(1.7)〗^t. what does the value of 900 represent in this situation and what does it tell you about the difference between the two studies?
