Jakeira is a research biologist who is studying a fast-growing bacteria strain of which the population size can double every 8 hours. To predict the colony size over the next week, she creates an equation that relates time in hours to the population size. Which function type best models this scenario?

A. a linear function
B. an exponential function
C. a quadratic function
D. a periodic function

B. an exponential function

is this right

Yes, that is correct. In this scenario, the population size is doubling every 8 hours, indicating exponential growth. Thus, an exponential function would best model this scenario.
