Answer:
Domain of C={1,2,3,4,5,6}
Range of C={24,28,32,36,40,44}
Step-by-step explanation:
We are given that Jenna knits scarves and sells them on Etsy an online market place.
Where C=Represents the cost in dollars
x=Number of scarves produced.
We have to find the domain and range of C.
Substitute x=1
$24
Substitute x=2
$28
$32
$36
$40
$44
Therefore, Domain of C={1,2,3,4,5,6}
Range of C={24,28,32,36,40,44}
If and
are odd positive integers, they are one more than a non-negative even number, i.e. there exists
such that
So, the first expression become
Similarly, we have
Now, the parity of these expressions depend on those of and
. We have four cases:
If both m and n are even:
is odd, since
is even, while
is even
If one of the two is odd and the other is even:
is even, since
is odd, while
is odd
If both are odd:
is odd, since
is even, while
is even
So, in all cases, one between (a+b)/2 and (a-b)/2 is odd, and the other is even.
