Isabel finds that the function below describes the number of books sold as a function of the number of months her ads have been posted. Isabel finds that the function below describes the number of books sold as a function of the number of months her ads have been posted.

Required:
How many books were sold after 8 months?

Answer 1

3000 were sold after 8 months

Explanation:

Answer 2

3000 books

Explanation:

The correct function that describes the number of books sold as a function of the number of months her ads have been posted is expressed as;

f(x) = 1000(∛x) + 1000

x is the number of months the ads have been posted

Required:

Number of books sold after 8 months

To get this we will substitute x = 8 into the expression given

f(8) = 1000(∛8) + 1000

f(8) = 1000(2) + 1000

f(8) = 2000 + 1000

f(8) = 3000

Hence the total number of books that were sold after 8 months is 3000 books
