Part A. Notice that
,
,
, and
. If we let
represent the number that is being cubed and
the result of that operation, we can create the function
whose domain and range are the set of all real numbers.
We can conclude that the table represent the cube function
.
Part B. To find the value of
, we just need to evaluate the total cost function
at
; in other word, we are going to replace
with 6 in the function:
Since
represent the number of days you are going to rent a car, it
represent the cost of renting a car for 6 days.
We can conclude that the value of
is $180, and it represent the cost of renting a car for 6 days.

Hey!
Let's solve this together.
5x+1 = 1+x2
Possible Answers: {5,4,3,2}
Lets start with 5.
5(5)+1 = 1+2(5)***
25+1 = 1+10
26 ≠ 11
So, 5 is NOT the answer.
Now, 4.
5(4)+1 = 1+(4)2
20+1 = 1+8
21 ≠ 9
So, 4 is NOT the answer.
Now, 3.
5(3)+1 = 1+(3)2
15+1 = 1+6
16 ≠ 7
So, 3 is NOT the answer.
Lastly, 2.
5(2)+1 = 1+(2)2
10+1 = 1+4
11 ≠ 5
So, 2 is NOT an answer.
So, the answer is: None of the above. None of them can be answers because none of them make the statement true.
***(In algebra, we start using parenthesis instead of the dot for multiplication when using numbers.)
Hope this helps!

Answer is 3x because u do 12-9 which gets three and since it was originally 12x and you don’t know what X is you just put the x on the 3 and get 3x
F (5,9)
You would divide everything by 5 then 9 over 5
