• Exponential

• Quadratic

A scientist began a study with a sample of 3,760 bacteria. He noticed that the number of bacteria in the sample after t days can be modeled by the equation f(t)=3,760(5)^t. In this equation, what does 5^t represent?

• The number of bacteria increases by 5 bacteria each day

• The number of bacteria increases by t bacteria after 5 days

• The number of bacteria increases by a factor of 5 each day

• The number of bacteria increases by a factor of t each day for 5 days
