A group of scientists is studying how a chemical affects the growth rate of bacteria. The scientists start with a group of 100 bacteria. They check the number of bacteria after each hour and determine that the growth rate for the bacteria is 4.5%. Which equation represents this exponential relationship? Select all that apply.

• f(t) = 100(1.45)^t

• f(t) = 100(1.045)^t

• f(t) = 100(1 + 0.45)^t

• f(t) = 10(1.045)2^t
