tia_tia [17]

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.

C(x)=4x+20

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

C(1)=4(1)+20=$24

Substitute x=2

C(2)=4(2)+20=$28

C(3)=4(3)+20=$32

C(4)=4(4)+20=$36

C(5)=4(5)+20=$40

C(6)=4(6)+20=$44

Therefore, Domain of C={1,2,3,4,5,6}

Range of C={24,28,32,36,40,44}
