Question

After plotting the data where t represents the number of hours since time t=0, Kieran used technology and determined the appropriate model to approximate the number of bacteria after t hours is f(t) = 5(4)t. Use the model Kieran created to predict the number of bacteria after 3 hours.

64
160
280
320

Answer 1

f(t) = 5(4)^t

f(3) = 5(4^3) = 5 * 64 = 320
