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?

The value '1000' in the first study indicate the number of bacteria initially (when t=0).

The value is '1.7' is the multiplier - there's an increase exponentially by 1.7 every given 't'

The value '900' in the second study indicate the number of bacterial initially (at t=0)

The first study has more number of bacterias at the beginning of the study
