Answer:
, 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.

4th degree, so the ends both point in same direction
positive leading coefient so both ends point up
factor it to see wheere the roots are
the roots are r1,r2,r3,r4 in P(x)=(x-r1)(x-r2)(x-r3)(x-r4)
factor
P(x)=(x-3)(x-2)(x+1)(x+3)
the roots are
3,2,-1,-3
disregard negative roots becasue you can't have negative time or something
3 or 2
