Answer 1

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

The amount of money Juan makes from selling x books is represented by a function.



f(x)=15xf(x)=15x



What is the practical range of the function?

All multiples of 20 between 0 and 300, inclusive.

All real numbers.

All integers from 0 to 20, inclusive.

All multiples of 15 between 0 and 300, inclusive.

Answer 2

is it all real numbers?

Answer 3

range would be the possible amount of money he would be able to make

if he sells no books, he makes $0
if he sells all books, he makes $300
if he sells n books, he makes $15*n

Answer 4

b?

Answer 5

I think b too

Answer 6

no, because it is impossible to sell only a fraction of a book

Answer 7

so making 1$ is not an answer hence all real numbers does not apply

Answer 8

ok idk what is it thats confusing

Answer 9

what are the possible amounts of money he could make selling books?

Answer 10

d

Answer 11

i would agree with D
its possible to make 0 if he doesnt sell any books
if he sells a couple of books, the amount of money he would get would have to be a multiple of 15
and if he sells all books, he would only make 300

Answer 12

so d?

Answer 13

Ok
It is C

Answer 14

x varies from 0 to 20 only
this is the practical domain

Answer 15

range not domain

Answer 16

thanks man come to the next post

Answer 17

it is D

Answer 18

Oh sorry
I though t domain


for practical domain: A

Answer 19

but he only has 20 books @3mar

Answer 20

but I am talking about range, which means: related to y, i.e 15*0>>>15*20

Answer 21

@bonnieisflash1.0

Answer 23

You need the practical domain: it is A
