In a lab, a scientist is growing bacteria for a study. The scientist begins with a bacteria population of b cells. She discovers that after 2 hours, the population of bacteria is

62 cells. If the population of the bacteria after these 2 hours is one million cells, what

was the population at the start? Explain how you found your answer.

The answer is below

Step-by-step explanation:

The growth of the bacteria is in the form of an exponential growth. It is given by the formula:

At 2 hours, the population is 62 cells, hence:

After another 2 hours (4 hours), the population is 1 million:

Put r = 4.844 in equation 1

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
