Neither, because for a function, each range has it own domain

No

domain is the set of numbers you can use in the function
range is the set of numbers you get from inputing the values from the domain

we actually have more numbers in the domain than numbers in the range
example
f(x)=x^2
if domain={1,-1}
becase of that square root
range={1} (we just list repeating values once)

so the number of elements in the range CANNOT be greater than the number of elements in the domain

Hello,

u_{1} =1*(8-7)=1*(2*4-(6+1))\\
 u_{2} =2*(10-7)=2*(2*5-(6+2))=2*(2*(4+1)-(6+2))\\
 u_{3} =3*(12-9)=3*(2*6-(6+3))=3*(2*(4+2)-(6+3))\\
 u_{4} =4*(14-10)=4*(2*7-(6+4))=4*(2*(4+3)-(6+4))\\




u_{10}=10*(2*(4+10)-(6+10))\\
=10*(28-16)


...\\\\
u_{n} =n*(2*(n+n-1)-(6+n))\\
=n*(4n-2-6-n)=n(3n-8)\\

Mai poured `2.6` liters of water into a partially-filled pitcher. The pitcher now contains `10.4` liters. Mai wants to know how
prisoha [69]

Answer: 7.8

Step-by-step explanation: If we want to find the amount that was in the pitcher before then we subtract 2.6 from 10.4 to find the original amount because if the pitcher were to contain an amount that only adds up to 10.4 before we add 2.6 then the number that adds with 2.6 to equal 10.4 is our answer

hence our answer 7.8

Use complete sentences to describe why Set A = { X | X is an even whole number between 0 and 2} = ∅
RoseWind [281]

Consider the Set A = {X | X is an even whole number between 0 and 2 } = \Phi.

Since, whole numbers are the set of numbers starting from zero upto infinity.

Even numbers are the numbers which are exactly divisible by '2'.

So, we have to find the even whole number between 0 and 2.

Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.

Therefore, there is no even whole number between 0 and 2.

So, this set is empty.

Therefore, A = { X | X is an even whole number between 0 and 2} =  \Phi
