Answer:
All real numbers
Step-by-step explanation:
Here, we want to get the domain
The domain refers to the possible x values of the function
As we can see, the plot extends thoroughout the entirety of the graph

numbers
Answer:
<h2>
</h2>
Step-by-step explanation:
According to the question,
∝
.......(1)
∝
.......(2)
From equation 1,2 let constant of proportionality be 
respectively.
⇒
.......(3)
⇒
.......(4)
From the above equations putting 4 into 3,
Let the new constant to the above equation be 
,
Given,if x=1, when z=4
⇒
Now if x=27, then z=?
⇒
⇒
Table 2 represents a proportional relationship because if you divide 3 divided by 2 you get 1.5 and you will get the same for 4.5 divided by 3, 6 divided by 4, 7.5 divided by 5
factors of 18: 1,2,3,6,9
factors of 30: 1,2,3,5,6, 10, etc.
The greatest number of book for each shelf is 6.
18/6=3 shelves
30/6 =5 shelves
5+3= 8 shelves
There will be 8 shelves for each book.
