Final answer:
The relationship between the number of bacteria (y) and the number of days (x) can be represented by the equation y = 6000 * (1.16)^x.
Step-by-step explanation:
The relationship between the number of bacteria (y) and the number of days (x) can be represented by the equation y = 6000 * (1.16)^x. This is because the population of bacteria is growing at a rate of 16% each day, so each day the population increases by 16% of the previous day's population.
