Answer 1

Answer:

Step-by-step explanation:

Juan has 20 books to sell. He sells the books for $15 each.

The range of the function is the set of all possible values of the dependent variable. The dependent variable here is the amount of money that is made and this amount depends on

the number of books, x sold

The amount of money Juan makes from selling books is represented by a fucntion. f(x)=15x

The maximum amount that can be made from 20 books at a rate of $15 each would be 20×15 = $300

The minimum amount that fan be made is $0 and this is when no book is sold. Let y = f(x). So the range is

0 lesser than or equal to y lesser than or equal to 300
