Domain : ![\{1,2,3,4\}](https://tex.z-dn.net/?f=%5C%7B1%2C2%2C3%2C4%5C%7D)
Range: ![\{2,4,6,8\}](https://tex.z-dn.net/?f=%5C%7B2%2C4%2C6%2C8%5C%7D)
Explanation:
It is given that Bev earns $2 a week.
Thus, for n number of weeks, we shall multiply $2 with n.
Where
is the number of weeks.
For 1 week, Bev earns
⇒ $2
For 2 weeks, Bev earns
⇒ $4
For 3 weeks, Bev earns
⇒ $6
For 4 weeks, Bev earns
⇒ $8
Thus, we can see that the domain is the number of weeks.
Hence, Domain : ![\{1,2,3,4\}](https://tex.z-dn.net/?f=%5C%7B1%2C2%2C3%2C4%5C%7D)
Also, the money earned is the range.
Hence, Range: ![\{2,4,6,8\}](https://tex.z-dn.net/?f=%5C%7B2%2C4%2C6%2C8%5C%7D)
