, where a is initial value.
Step-by-step explanation:
We have been given that Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive the email increases by a factor of 4 every 9.1 weeks. We are supposed to write the function to represent the given scenario.
Our function will be in form of , where,
a = Initial value,
b = Factor of increase,
= Linear function to determine the time.
Since number of people receiving email increase every 9.1 weeks, that is 1 people is 9.1 weeks, so slope of the increase would be .
Increase in number of people in t weeks would be .
Upon substituting our given values in growth function, we will get:
Therefore, our required function would be , where a is initial value.
