What is he saying he was a
Answer:
Options (1) and (5)
Step-by-step explanation:
Expression that defines the function is,

Option 1





So,
is false.
Option 2
f(0) = 
= 
True.
Option 3
f(1) = 
= 
= 2
Therefore, f(1) = -1 is false.
Option 4



Therefore, f(2) = 1 is false.
Option 5
f(4)



True.
Options (1) and (5) are the correct options.
Yes you have a good example.
x = number of cookies
2*x = total amount spent on cookies at $2 each
2x-3 = amount you pay after the $3 discount is applied one time for the entire order
-------------
a more numeric example may be this
Lets say you bought 12 cookies, so x = 12
This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply
However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.
<u>Answer:</u>
The correct answer option is d. 9.
<u>Step-by-step explanation:</u>
We are given an expression
and we are supposed to simplify it.
We can also write
as
.
We know the power rule
which means that to raise a power to a power you need to multiply the exponents.
So multiplying the exponents to get:

3 gets cancelled by 3 so we are left with:

Therefore, the correct answer option is d. 9.
